one-year
UK: wʌn jɪə | US: wʌn jɪr
adj. lasting for or relating to a period of twelve months
The term "one-year" is a straightforward compound adjective formed by combining "one" (from Old English "ān," meaning "single" or "a unit") and "year" (from Old English "gēar," referring to the Earth's orbital cycle). The hyphenated form explicitly links the two concepts to describe a duration of exactly twelve months, commonly used in contexts like contracts, milestones, or developmental periods.
