twoweek

Twoweek is a nonstandard compound used to denote a period of fourteen days. In formal writing, the preferred forms are "two weeks" or "a two-week period." The term may appear in informal notes, data fields, or shorthand labels, but is rarely used in polished prose.

Etymology and synonyms: It is formed by combining two and week. A traditional, widely used synonym is fortnight, especially in British English, which literally means fourteen nights, though it is less common in American English.

Usage: In planning, scheduling, and payroll, the concept is common. The hyphenated form "two-week" is standard when used as an adjective (a two-week deadline, a two-week sprint). The noun phrase "two weeks" or the adverbial phrase "every two weeks" are clearer in ordinary text. The single-word form "twoweek" is almost never correct in standard English.

Ambiguity and care: Some contexts use "biweekly" to indicate every two weeks, but this can also mean twice weekly, causing confusion. Writers should prefer "every two weeks" or "two-week" to avoid misinterpretation.
