'Aide' (with an e) = a person who assists. 'Aid' (no e) = help, resources, or the verb 'to help'. Below: a compact rule, spacing traps, clear grammar points, many concrete wrong/right pairs across work, school, and casual contexts, three ready-to-copy rewrites, and a quick checklist to fix sentences fast.
Quick answer
'Aide' = assistant (person). 'Aid' = help/support (noun) or to help (verb).
- If you mean a person: use 'aide'. Example: 'She is the senator's aide.'
- If you mean help, supplies, or the action of helping: use 'aid'. Example: 'They sent disaster aid.'
- As a verb, always use 'aid' (never 'aide'). Example: 'Volunteers will aid the victims.'
Spacing and common typo traps
Most mistakes come from hearing a phrase and guessing the written form. Watch for these pitfalls:
- Don't split or add letters: 'aid e' or 'ai de' are wrong.
- Check plural forms: 'aides' = assistants; 'aids' = devices or types of help (hearing aids).
- Hyphenation can change meaning: use 'first aid' as a noun, hyphenate when it modifies a noun (first-aid kit).
Core grammar points
Keep these rules in hand when you edit:
- 'Aide' is a noun naming a person who assists (teacher's aide, campaign aide, personal aide).
- 'Aid' is either a noun (help, relief supplies) or a verb (to help).
- Use 'aid' as the verb: 'They will aid the recovery.' Never write 'aide' as a verb.
Hyphenation notes
Hyphens don't affect 'aide' vs 'aid' directly, but they matter for compounds:
- As a noun: 'first aid' (I'll give you first aid).
- As an adjective before a noun: 'first-aid kit', 'first-aid training.'
- When unsure, rewrite to avoid awkward hyphenation (e.g., 'training in first aid').
