Note on Usage

"Five-year" is a compound adjective and is typically used with a hyphen when it appears before a noun (e.g., "a five-year plan"). Without the hyphen, it may be misinterpreted as a noun phrase (e.g., "five year plans" is less standard). It is not used as a standalone noun; the noun form is "five years" (e.g., "a period of five years").
