# 03. The syllable, word stress, rhythm and intonation

## 1. The syllable

An English syllable has an optional **onset** of up to three consonants, a **nucleus** (a vowel, or a syllabic /l n m/ in unstressed syllables), and an optional **coda** of up to four consonants:

(C)(C)(C) V (C)(C)(C)(C)

| shape | example |
| --- | --- |
| V | *eye* /aɪ/, *a* /ə/ |
| CV | *see* /siː/ |
| CVC | *cat* /kæt/ |
| CCVC | *stop* /stɒp/ |
| CCCVC | *string* /strɪŋ/ |
| CVCC | *help* /help/ |
| CVCCC | *texts* /teksts/, *sixth* /sɪksθ/ |
| CCCVCCC | *strengths* /streŋkθs/ (CCCVCCCC with the epenthetic [k]) |

Reynolds 2026 §7.7 gives *eye* and *strengths* as the two ends of the scale and notes that such long clusters are uncommon across languages, which is why learners insert vowels (Spanish speakers' *estop* for *stop*).

### 1.1 Onsets

| onset type | members | gaps and notes |
| --- | --- | --- |
| any single consonant | all except /ŋ/; /ʒ/ only in loans (*genre*) |  |
| plosive + liquid | /pl pr bl br tr dr kl kr ɡl ɡr/ | no */tl dl/ (except loans *Tlingit*) |
| fricative + liquid | /fl fr θr ʃr/ (*shrink*) | /sl/ but no */sr/; /vl, vr/ only in loans (*Vladimir*) |
| C + /w/ | /tw dw kw ɡw sw θw/ (*twin, dwell, quick, Gwen, swim, thwart*) |  |
| C + /j/ | /pj bj tj dj kj ɡj fj vj mj nj hj lj/ before /uː, ʊə/ (*pure, beauty, cute, few, music, huge*) | /tj dj nj sj lj/ only in accents without yod-dropping ([01](https://md.mova.elamur.ai/free/en/docs/languages/en/01-consonants/) §2.7) |
| /s/ + plosive or nasal | /sp st sk sm sn/ | /sf/ only in Greek loans (*sphere*) |
| /s/ + plosive + liquid/glide | /spl spr str skr skw skj spj/ (*split, spring, string, scream, square, skew, spew*) | the only three-consonant onsets |

### 1.2 Codas

Codas are freer. Up to four consonants occur: *texts* /ksts/, *sixths* /ksθs/, *glimpsed* /mpst/. Most long codas are made by inflection: the plural, third-person and past suffixes /s z t d/ are added to codas that are already complex ([04. Connected speech and morphophonology](https://md.mova.elamur.ai/free/en/docs/languages/en/04-connected-speech/) §6). Within a morpheme, the coda follows sonority (nasals and liquids before obstruents: *help, film, tent*); suffixes may break it (*lapse*).

Constraints worth knowing:

- /h/ never closes a syllable; /ŋ/ never opens one; /j w/ never close one (they become parts of diphthongs).
- A stressed syllable must be **heavy**: either a free vowel (*see*) or a checked vowel + consonant (*sit*); */sɪ/ is not a word ([02. Vowels](https://md.mova.elamur.ai/free/en/docs/languages/en/02-vowels/) §1).
- After a free vowel, the coda is limited: two consonants at most within a morpheme, and they must be coronal (*paint, fiend, ounce*).

### 1.3 Syllable division

English syllable boundaries are fuzzy between vowels. A consonant after a short stressed vowel belongs to both syllables (it is **ambisyllabic**): *happy, city, butter*. This is why English spelling doubles the consonant after a checked vowel in *hopping, bigger* ([06. Spelling rules: inflection, derivation, compounds and national standards](https://md.mova.elamur.ai/free/en/docs/languages/en/06-spelling-rules/) §2), and why dictionaries disagree on where to hyphenate. British hyphenation tends to follow morphology (*know-ledge*), American hyphenation pronunciation (*knowl-edge*).

## 2. Stress: what it is

Stress is the prominence of a syllable, made by a mix of loudness, length, full vowel quality and, above all, a pitch movement when the syllable carries the accent of a phrase. English has three levels in a word: **primary** (/ˈ/), **secondary** (/ˌ/), and **unstressed**, the last usually with a weak vowel ([02. Vowels](https://md.mova.elamur.ai/free/en/docs/languages/en/02-vowels/) §5): *ˌphotoˈgraphic, ˈphotoˌgraph*.

Stress is **free**: it can fall on any syllable, and it distinguishes words: *ˈinsight* vs *inˈcite*, *ˈbillow* vs *beˈlow*, *ˈrecord* (n.) vs *reˈcord* (v.). But it is largely **predictable** from the word's origin, class and syllable weight.

## 3. Native and early words: stress the root

Native and early loan words stress the first syllable of the root, and prefixes and suffixes stay unstressed (or take secondary stress):

- *ˈfather, ˈmother, ˈwater, ˈhappy, ˈyellow, ˈwomen*
- prefixes: *beˈlieve, forˈget, aˈrise, unˈkind* (*un-* takes secondary or even stress: Sweet NEG I §919 lists *ˈunbeˈlief, ˈmisˈconduct* as words "balanced" between prefix and body)
- suffixes: *ˈkindness, ˈhopeful, ˈfriendly, ˈfriendship, ˈwaiting* (all stress-neutral, §5.1)

Sweet NEG I §880 states the general principle of Present English stress: subordinate words and elements (form-words, prefixes, endings) are weak, the main element strong.

## 4. Latinate words: the weight rule

Latin and French words, which make up most of the dictionary, follow a version of the Latin stress rule, adapted to English:

1. **Nouns** (and most adjectives): ignore the last syllable; stress the second-to-last (penult) if it is heavy (long vowel or closed); otherwise the third-to-last (antepenult). heavy penult: *aˈgenda* (closed /dʒen/), *aˈroma* (long /əʊ/), *diploma* light penult: *ˈcinema, ˈcamera, aˈmerica, ˈcanada*
2. **Verbs** (and some adjectives): consider the last syllable; stress it if it is heavy, i.e. has a long vowel or ends in two consonants; otherwise stress the penult. heavy final: *mainˈtain, obˈey, torˈment, colˈlapse, eˈrupt* light final: *ˈvomit, deˈvelop, aˈstonish, ˈedit*
3. **Words with *-ate*, *-ize*, *-y* endings** stress the antepenult or earlier: *ˈeducate, ˈrealize, ˈphotograph, phoˈtography*.

The rule has exceptions, and loans from French often keep final stress: *poˈlice, ciˈgar, hoˈtel, gaˈrage* (GA; BrE ˈgarage), *maˈchine, caˈreer, ballet* (BrE ˈballet, AmE balˈlet).

### 4.1 How stress is distributed (CMUdict)

Counts over the first pronunciation of each headword in CMUdict (135 166 entries, many proper names; counted 2026-10-17):

| syllables | headwords | stress pattern (1 = primary, 2 = secondary, 0 = none) |
| --- | --- | --- |
| 1 | 16 384 | — |
| 2 | 58 032 | first syllable primary: **87.6%** (10: 43 064, 12: 7 780); second: 11.4% (01: 5 728, 21: 875) |
| 3 | 34 683 | most frequent: 010 (12 167, e.g. *banana*), 100 (12 097, *cinema*), 102 (4 770, *dinosaur*), 120 (1 841), 210 (1 531) |
| 4 | 12 529 |  |
| 5 | 3 531 |  |
| 6 | 748 |  |

Initial stress dominates disyllables, as the native principle and the noun rule predict; final stress is mostly in verbs and French loans.

### 4.2 Noun–verb stress pairs

About a hundred disyllabic words of Latin or French origin are stressed on the first syllable as nouns (and adjectives) and on the second as verbs:

| noun/adjective | verb |
| --- | --- |
| *ˈrecord* | *reˈcord* |
| *ˈpresent* | *preˈsent* |
| *ˈobject* | *obˈject* |
| *ˈcontract* | *conˈtract* |
| *ˈconduct* | *conˈduct* |
| *ˈcontest* | *conˈtest* |
| *ˈconvict* | *conˈvict* |
| *ˈdesert* | *deˈsert* (also noun *dessert*) |
| *ˈimport, ˈexport* | *imˈport, exˈport* |
| *ˈincrease, ˈdecrease* | *inˈcrease, deˈcrease* |
| *ˈinsult* | *inˈsult* |
| *ˈpermit* | *perˈmit* |
| *ˈproduce* | *proˈduce* |
| *ˈprogress* | *proˈgress* |
| *ˈprotest* | *proˈtest* |
| *ˈrebel* | *reˈbel* |
| *ˈsubject* | *subˈject* |
| *ˈsuspect* | *susˈpect* |
| *ˈtransfer* | *transˈfer* |
| *ˈupset* | *upˈset* |

The pattern spreads: GA has *ˈaddress* (noun) beside *adˈdress* (verb), and *ˈresearch* is now common for the noun in both standards. Jespersen MEG VI 11.9 treats this "difference in stress" as one of the means by which English distinguishes noun and verb without adding a formative, together with vowel change (*bleed–blood*, 11.2–11.8) and consonant change (*advise–advice*, chapter XII). CMUdict lists both stresses for many of these words; a speech front end would need the tag to choose ([10. Word classes](https://md.mova.elamur.ai/free/en/docs/languages/en/10-word-classes/) §5).

## 5. Stress and suffixes

Suffixes fall into three classes by what they do to stress. This classification is standard in English morphology; Ben Hedia 2019 (§4.2, on Lexical Phonology and later stratal approaches) discusses the related division of affixes into "level 1" (Latinate, stress-shifting, phonologically integrated) and "level 2" (Germanic, stress-neutral, separable) in her study of gemination at morpheme boundaries; her measurements (ch. 8) do not support a clean two-level split, finding instead a gradient by affix.

### 5.1 Stress-neutral suffixes

The stem keeps its stress, and the suffix is unstressed: *-ness, -less, -ful, -ly, -er* (agent), *-ing, -ed, -s, -ish, -dom, -hood, -ship, -ment* (mostly), *-able* (mostly), *-ize* (mostly).

*ˈcareful, ˈcarelessness, deˈvelopment, ˈmotherhood, ˈreadable, ˈcriticize.*

### 5.2 Stress-attracting suffixes

The suffix itself takes the primary stress: *-ee* (*employˈee, trainˈee*), *-eer* (*engiˈneer, volunˈteer*), *-ese* (*Japaˈnese, journaˈlese*), *-ette* (*kitchenˈette, cigaˈrette*), *-esque* (*pictuˈresque*), *-ique* (*techˈnique, boutique*), *-oon* (*balˈloon, carˈtoon*), *-ade* (*lemoˈnade*), *-aire* (*millionˈaire*).

### 5.3 Stress-shifting (pre-stressing) suffixes

The stress moves to the syllable right before the suffix, and the vowels of the stem change accordingly ([02. Vowels](https://md.mova.elamur.ai/free/en/docs/languages/en/02-vowels/) §5.3):

| suffix | stress falls on | examples |
| --- | --- | --- |
| *-ity* | syllable before | *ˈmajor → maˈjority, ˈpersonal → persoˈnality, aˈble → aˈbility* |
| *-ic, -ical* | syllable before | *ˈatom → aˈtomic, ˈhistory → hisˈtoric(al), ˈhero → heˈroic* |
| *-ion, -ian, -ial, -ious, -ient* | syllable before | *ˈeducate → eduˈcation, ˈmusic → muˈsician, ˈpresident → presiˈdential, ˈmystery → mysˈterious* |
| *-ify, -ity, -ometer* | syllable before | *ˈsolid → soˈlidify, therˈmometer, ˈspeed → speeˈdometer* |
| *-ate* (verbs), *-ize* in some | antepenult (2 before) | *ˈcertify, ˈdemonstrate* |
| *-y* in Greek *-graphy, -logy, -nomy, -metry* | syllable before the ending | *ˈphotograph → phoˈtography, biˈology, eˈconomy* |
| *-al* (adj.) | as in nouns (weight rule) | *ˈpersonal, enviˈronmental, aˈrrival* |

## 6. Stress in compounds and phrases

### 6.1 Compound stress vs phrase stress

A **compound** usually has **fore-stress** (primary on the first element); a **phrase** has **end-stress** (primary on the last word):

| compound (fore-stress) | phrase (end-stress) |
| --- | --- |
| *a ˈblackbird* (a kind of bird) | *a black ˈbird* (a bird that is black) |
| *the ˈWhite House* | *a white ˈhouse* |
| *a ˈgreenhouse* | *a green ˈhouse* |
| *a ˈdancing teacher* (one who teaches dancing) | *a dancing ˈteacher* (a teacher who dances) |
| *ˈEnglish teacher* (teaches English) | *English ˈteacher* (from England) |

Sweet NEG I §§889–929 analyses this at length. He calls the phrase pattern "even stress" (both words strong, the last strongest) and the compound pattern "uneven stress", and observes (§900) that noun + noun compounds take uneven (fore-) stress when a causal or purpose relation is implied (*toyshop*, *watchdog*). §§906–911 extend uneven stress to verb + noun compounds, to noun + participle adjectives, to noun or adjective + verb compounds.

### 6.2 Compounds with end-stress

Not all compounds take fore-stress. Typical end-stressed compounds:

- material or ingredient as first element: *apple ˈpie, stone ˈwall, paper ˈbag, cheese ˈsandwich* (but *ˈcheesecake*);
- location or time: *kitchen ˈsink, summer ˈholiday, morning ˈpaper* (but *ˈmorning sickness*);
- proper names of places with *Street* vs *Road*: *ˈOxford Street* but *Oxford ˈRoad, Fifth ˈAvenue, Madison Square ˈGarden*;
- many adjective + noun: *Christmas ˈEve, Prime ˈMinister, town ˈhall*.

Schäfer 2018 (§3.1.2, "Semantic transparency and compound stress") reviews the literature on compound stress and its relation to the meaning of English noun–noun compounds; no single rule predicts it, and dictionaries record it word by word. Group-compounds joined by *and* or a preposition throw the stress on the second element: *cup and ˈsaucer, bread and ˈbutter* (Sweet NEG I §923).

### 6.3 Stress shift (the rhythm rule)

An end-stressed word or phrase moves its stress forward when a stressed word follows, to avoid two adjacent stresses: *thirˈteen* but *ˈthirteen ˈmen*; *Japaˈnese* but *ˈJapanese ˈgarden*; *Piccaˈdilly* but *ˈPiccadilly ˈCircus*; *ˈwell-ˈknown* but *a ˈwell-known ˈwriter*. Sweet NEG I §929 describes the same thing for "assumptive" (attributive) use: an even-stress compound or group put before a noun throws its stress on the first element.

### 6.4 Phrasal verbs

A phrasal verb stresses the particle: *give ˈup, look ˈafter* (prepositional verbs keep the stress on the verb: *ˈlook at*). The derived nouns take fore-stress: *a ˈtakeover, a ˈbreakdown, a ˈlookout* ([18. Compounding, conversion and the minor processes](https://md.mova.elamur.ai/free/en/docs/languages/en/18-compounding-conversion-minor/) §2.5).

## 7. Rhythm

English is **stress-timed** in tendency: stressed syllables come at roughly regular intervals, and the unstressed syllables between them are compressed. Hence the strong reduction of unstressed vowels ([02](https://md.mova.elamur.ai/free/en/docs/languages/en/02-vowels/) §5), the weak forms of function words ([04](https://md.mova.elamur.ai/free/en/docs/languages/en/04-connected-speech/) §2) and the rhythm rule (§6.3). The sentence *ˈCats ˈchase ˈmice* and *The ˈcats have been ˈchasing the ˈmice* take a similar time to say, because each has three stresses. Reynolds 2026 §7.8.3 describes English rhythm in these terms and warns that languages differ less sharply than the old stress-timed/syllable-timed division suggests.

## 8. Intonation in outline

Intonation is the pitch pattern of an utterance. Three choices are made:

1. **Tonality**: how speech is divided into intonation phrases (*My brother who lives in Paris* | vs *My brother, | who lives in Paris, |*: the restrictive vs non-restrictive relative clause).
2. **Tonicity**: where the **nucleus** (the main accent) falls. By default it is on the last content word: *I'm going to ˈLondon*; it moves to mark contrast or to leave given material unaccented: *I'm going TO London, not FROM it*; *Have you seen my keys? – I've LOST my keys* (the repeated *keys* is deaccented).
3. **Tone**: the pitch movement on the nucleus:

| tone | typical use | example |
| --- | --- | --- |
| fall ↘ | statements, wh-questions, commands | *It's raining.↘ Where are you going?↘* |
| rise ↗ | yes/no questions, lists not finished, echo questions | *Are you ready?↗ You did WHAT?↗* |
| fall-rise ↘↗ | reservation, implication, contrast | *I like the COLOUR↘↗ (but not the shape)* |
| rise-fall ↗↘ | strong feeling, being impressed | *It was ↗↘MARvellous!* |
| level → | routine, unfinished |  |

Sweet NEG I §§661–663 and §84 give the classic statement: the falling tone expresses statement, the rising tone a question. Reynolds 2026 §10.4.3 and §10.5.7 note that yes/no questions usually rise and wh-questions usually fall, but that the link between tone and sentence type is a tendency, not a rule. **Uptalk** (high rising terminals on statements), widespread in Australia, New Zealand and among young speakers in the US and Britain, is described by Hejná & Walkden 2022 §2.2.3 as a present-day change with functions such as checking understanding.

Intonation belongs to pragmatics as much as to phonology; chapters [29](https://md.mova.elamur.ai/free/en/docs/languages/en/29-ellipsis-word-order-information-structure/) and [26](https://md.mova.elamur.ai/free/en/docs/languages/en/26-questions/) treat focus, given and new information and question types.

## 9. How Mova handles syllables and stress

Not at all, at present: Mova works on written text, and no component counts syllables or assigns stress. Three places in morphology would profit from it and currently use spelling approximations instead:

- **Comparison** (*-er/-est* vs *more/most*) depends on the number of syllables and on final unstressed syllables; Mova takes the form from the lexicon and does not generate unknown comparatives by rule beyond simple suffixing ([15. Adjectives and adverbs](https://md.mova.elamur.ai/free/en/docs/languages/en/15-adjectives-adverbs/) §2.6).
- **Consonant doubling** depends on stress (*preˈfer → preferred*, but *ˈoffer → offered*); the fallback inflector `suffix()` in `en/src/morph.rs` does not double at all and relies on the lexicon for every known verb ([06. Spelling rules: inflection, derivation, compounds and national standards](https://md.mova.elamur.ai/free/en/docs/languages/en/06-spelling-rules/) §2.4).
- **Noun–verb stress pairs** (*ˈrecord–reˈcord*) are homographs to Mova, told apart by the tagger.
