isn'r (isn't)

You typed or read "She isn" - the apostrophe is missing. Either write the contraction "She isn't" or the full form "She is not," depending on tone and emphasis.

Short answer

"She isn" is incorrect. Use She isn't (contraction) for everyday speech and many workplace messages, or She is not for formal writing or emphasis.

She isn → incorrect (missing apostrophe)
She isn't → informal/neutral (conversational tone, most emails, chat)
She is not → formal or emphatic (reports, legal text, strong contrast)

Core explanation: what's wrong with "She isn"

The apostrophe in a contraction marks omitted letters. "Isn't" stands for "is not" - the apostrophe replaces the missing "o". Without it, "isn" is a misspelling, not a valid contraction.

You can fix the error two ways: add the apostrophe (She isn't) or expand to the full form (She is not) when you want formality or emphasis.

Contraction: She isn't = she is not (apostrophe replaces the "o")
Full form: She is not - use for emphasis or formal register
Speak it aloud: if you naturally say "isn't," write the contraction; if you say "is not" slowly for stress, write the full form

Wrong: She isn ready for the interview.
Right: She isn't ready for the interview.
Also right: She is not ready for the interview.

Spacing: common contraction mistakes

Apostrophes attach directly to letters: isn't has no spaces. Typical errors are missing the apostrophe (isnt) or adding stray spaces (isn 't, is n't).

Scan the word visually - fixing spaces and inserting the apostrophe usually solves the problem.

Correct: She isn't here.
Wrong: She isnt here. / She isn 't here. / She is n't here.
Fix: Remove stray spaces and insert the apostrophe between n and t.

Wrong: She isnt sure when she'll arrive.
Right: She isn't sure when she'll arrive.
Wrong: She isn 't available right now.
Right: She isn't available right now.

Hyphenation: don't use hyphens for contractions

Hyphens join words or break them at line ends; they do not replace apostrophes. Never write She-isn't or She-isn.

If a contraction falls at a line break, rewrite the sentence instead of inserting hyphens.

Wrong: She-isn't available.
Right: She isn't available. Or rephrase: She is not available.
If a line break causes trouble, rewrite the sentence rather than hyphenating the contraction.

Usage: Wrong: She-isn't joining the meeting.
Right: She isn't joining the meeting.

Real usage and tone: choose isn't vs is not

Use She isn't in spoken language, many workplace messages, and casual writing. Use She is not for formal documents, academic or legal text, or to stress the negation.

When in doubt in professional writing, prefer the full form or follow company style guidance.

Casual or conversational → She isn't
Formal writing, emphasis, or contrast → She is not
If unsure in professional contexts, choose the full form

Work (email, neutral): She isn't available for a call this afternoon; can we reschedule?
Work (report, formal): She is not listed as a co-investigator on the study.
Work (chat, casual): She isn't joining the stand-up today.
School (email to professor): She is not able to submit the assignment by the deadline due to illness.
School (group message): She isn't contributing to this section - we should reassign tasks.
Casual (text): She isn't coming out tonight - she's got other plans.

Memory trick and a tiny checklist

Two quick tricks and a three-step checklist to catch missing apostrophes every time.

Memory trick: Hear the dropped "o." If you say "isn't" naturally, add the apostrophe.
Visual trick: Imagine a tiny bridge (') where the missing "o" used to sit: is o t → isn't.
Quick checklist: 1) Search for isnt/isn/is n't. 2) Insert apostrophe (isn't) or expand (is not). 3) Read aloud to check tone.

Example: Before: She isnt free. After: She isn't free. Or for emphasis: She is not free.
