thoughtout

Thoughtout is generally seen as a nonstandard or incorrect one-word form of the adjective thought-out or the stronger variant well-thought-out. In standard English, the single-word form thoughtout is not widely accepted; the preferred spellings are thought-out (hyphenated) or well-thought-out when used as a modifier before a noun. The two-word sequence thought out is typically a verb phrase meaning to think through or devise, as in “we thought out a plan.”

As an adjective before a noun, common and accepted spellings include thought-out and well-thought-out: for example, “a thought-out strategy” or “a well-thought-out proposal.” When used predicatively after a linking verb, the expression usually appears as “is thought out” or “has been thought out,” and the single-word form is rarely appropriate in formal writing.

Origin and usage notes: the term is built from the verb think out and the past participle thought, producing a compound adjective that signals careful planning or thorough consideration. Because of its compound nature, hyphenation is often used to clarify meaning and improve readability. The all-in-one spelling thoughtout is uncommon outside branding or very casual contexts and is generally treated as a misspelling in standard prose.
