in tact (intact)

Short answer: intact is one word. Writing "in tact" (two words) is a spacing error-replace it with intact or use a clearer rewrite.

Below: quick rules, real-world wrong→right fixes (work, school, casual), copy-paste rewrite templates, and a fast checklist for edits.

Quick answer

Use intact as one word. "In tact" is incorrect.

intact = one-word adjective meaning whole, undamaged, or unaltered.
Splitting it into "in tact" makes it read like the preposition in + tact, which is wrong in this meaning.
Fix: replace "in tact" → "intact", or rewrite (remain intact, arrive intact) or substitute a synonym (undamaged, whole, unaltered).

Core explanation: why intact is one word

Intact is a single adjective in modern English. Although it comes from Latin roots (in- + tactus), it's now treated as a single lexical item. Breaking it into two words misrepresents its function and meaning.

Part of speech: adjective (not a preposition + adjective construction).
Meaning: whole, undamaged, unaltered.
Usage tip: think of it as one block-if you mean "undamaged," type intact.

Spacing and hyphenation: common traps

Writers add a space because they hear two syllables or try a hyphen, but neither is correct. Don't use "in tact", "in-tact", or "in-tact".

Correct: intact
Incorrect: in tact / in-tact / in-tact
Hyphens belong in compounds (well-known), not inside a single adjective like intact.

Grammar: where intact fits in a sentence

Intact appears before nouns (attributive) or after linking verbs (predicative). Common verb combinations: remain intact, keep intact, leave intact, arrive intact.

Attributive: an intact package, an intact file

Verbs to watch for: remain, keep, leave, arrive, preserve
