Quick answer
Say "true to one's word" (singular). It means someone kept a promise or followed through. Common alternatives that often read better: "kept her word," "kept his promise," or "followed through."
- "Word" = a promise or commitment (singular), not the literal words someone spoke.
- Works with any pronoun: "true to my word," "true to your word," "true to their word."
- If "true to her words" appears, swap to the singular or use an active verb for clarity.
The correct idiom: "true to one's word"
The idiom uses the singular noun "word" because it refers to a promise or commitment, not to individual utterances. Saying "true to her words" shifts focus to literal sentences and sounds awkward when you mean "she kept her promise."
Common, clear rewrites:
- "She was true to her word."
- "He kept his promise."
- "They followed through on that commitment."
Keep the idiom intact when you want the idiomatic meaning; use an active verb when you want directness.
Form notes: hyphenation, spacing, and grammar
Hyphenation
The idiom contains no hyphens. Treat "one's word" as two words: a possessive plus a noun. Hyphens are not needed.
Spacing
Watch for accidental splitting or merging when you type quickly. The correct form is two words in the pattern: [adjective] + "to" + [possessive] + "word" (e.g., "true to his word").
Grammar
"True to" functions as an adjective phrase modifying the subject: "She was true to her word." Using "words" is grammatical but nonidiomatic when you mean promise; it makes the phrase sound literal or clumsy.

Seeing the idiom in context helps you spot and fix the wrong version quickly. Below are natural examples across common settings.
- Work: "The manager promised updated reports each Friday; she was true to her word."
- School: "He said he'd finish the lab early and was true to his word."

How to fix your own sentence
Fixes range from a simple swap to a natural rewrite. Read the whole sentence after changing it to ensure tone and flow stay right.
- Step 1: Identify whether you mean "promise/commitment" or "literal words."
- Step 2: If you mean promise, replace "words" with "word" or use an active verb ("kept," "followed through").
- Step 3: Reread for rhythm and tone; adjust pronouns or tense if needed.
Sample rewrites:
- Original: "This plan will work if everyone stays late and is true to their words."
Rewrite: "This plan will work if everyone stays late and is true to their word." - Original: "He was true to his words and finished the task."
Rewrite (clearer): "He kept his word and finished the task."
- Original: "Are you true to your words on this?"
Rewrite (natural): "Can I trust you'll keep your word on this?"
A simple memory trick
Associate the idiom with the idea of a single promise. Picture "word" as one compact unit-a pledged commitment-rather than separate spoken phrases. That mental image makes "word" feel right and "words" feel off when you mean a promise.
- Picture a handshake or signed note labeled "word."
- When you hear the phrase, ask: "Promise or literal phrasing?" If promise → use "word."
- Search your document for "true to * words" and fix in bulk.
Similar mistakes to watch for
Form errors often cluster. When you see one, scan nearby text for related slips.
- Splitting closed compounds (e.g., "every day" vs. "everyday").
- Hyphen confusion (e.g., "re-sign" vs. "resign").
- Using plural where the idiom requires singular ("word").
- Mixing verb forms instead of choosing a clear active verb ("kept" vs. "was true to").
