## What it is about

The paper presents MAGEAD, a finite-state morphological analyzer and generator for Modern Standard Arabic and its dialects. Dialect morphology shares the root-and-pattern system with MSA, but orthography in dialects is not standard, and speakers mix morphemes from several varieties inside one word. The design has three levels: a lexeme with features (for example POS, person, aspect), morphemes, and the surface string. It uses a multitape finite-state model after Kiraz (2000), with five tiers: pattern and affixes, root, vocalism, phonology, and orthography. The fifth tier is new, so that inconsistent spellings can be modelled apart from sound. Templates are built from a context-free grammar of morpheme order that covers all dialects. Rewrite rules handle sound changes such as the t-to-d change in form VIII before z, d or dh. The work is in progress: no evaluation is reported, and the only test corpus available is the MSA Penn Treebank.

## Ideas

- I1. Store the lexeme as the deepest key and the root only as an index field. The paper argues that meaning cannot be predicted from root and pattern (its maktab and maktaba example), so a lexicon keyed on the root would mislead. The rule belongs in [The lexicon](https://md.mova.elamur.ai/free/en/docs/languages/hbo/10-lexicon/), and for Aramaic in [The lexicon of Biblical Aramaic](https://md.mova.elamur.ai/free/en/docs/languages/arc/lexicon/).
- I2. Keep a separate orthographic tier from the phonological one. When a text is spelled in several ways, as Targumic or Zoharic Aramaic often is, the spelling and the pronunciation can be stored separately, so one analysis serves several spellings. Candidate design note for [Script and phonology](https://md.mova.elamur.ai/free/en/docs/languages/arc/script-phonology/) and [1. Script and pointing](https://md.mova.elamur.ai/free/en/docs/languages/hbo/01-script/).
- I3. A regression suite of surface and analysis pairs, which the paper plans and which is cheap to build: a list of word forms with their expected analysis, run on each change of the rules. For Mova, take weak verbs from [The weak verbs](https://md.mova.elamur.ai/free/en/docs/languages/hbo/07-weak-verbs/) and check each morphophonological rule against them.

## For Mova

I1 and I2 are design decisions for [The lexicon](https://md.mova.elamur.ai/free/en/docs/languages/hbo/10-lexicon/) and [Script and phonology](https://md.mova.elamur.ai/free/en/docs/languages/arc/script-phonology/). I3 is a test suite for `tools/hbo` and the verb chapter [The verb](https://md.mova.elamur.ai/free/en/docs/languages/hbo/06-verb/), paired with the weak-verb rules in [The weak verbs](https://md.mova.elamur.ai/free/en/docs/languages/hbo/07-weak-verbs/). No numbers are reported in the paper, so nothing here is a measured gain.
