# isn

«isn» in Mova's school dictionary: **the first part of the short form «isn't», which means «is…** — its meaning for a pupil, its sense in the lessons and examples.

### part of speech

fragment (isn — part of «isn't» = is not)

### meaning for a pupil

Not a full word: «isn» is the first part of the short form «isn't», which means «is not». Written alone it appears only when the apostrophe and «t» are cut off. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/I/isn/#m1)

### sense in the lessons

In English lessons «isn't» is a contraction: the apostrophe stands where the letter «o» was left out of «is not». It is used in speech and friendly writing: «It isn't fair», «Isn't it lovely?». In tag questions: «It's cold, isn't it?».

- Nana, it isn’t six o’clock yet. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/I/isn/#x7)

### note

Always write «isn't» with an apostrophe between «n» and «t». Full form: «is not». Do not write «isnt» or «is'nt». In formal writing use «is not». «Ain't» is very informal and counted wrong in school writing.
