first-quarter
UK: ˌfɜːst ˈkwɔːtə | US: ˌfɜːrst ˈkwɔːrtər
adj. relating to or occurring in the first quarter of a year, fiscal period, or lunar phase
n. the first quarter of a year, fiscal period, or lunar phase
The word combines "first," derived from Old English fyrst (foremost in time/rank), and "quarter," from Latin quartarius (a fourth part). Together, they denote the initial segment of a four-part division, originally applied to lunar phases and later extended to fiscal/calendar periods. The hyphenated form emerged in the 19th century to function as a compound adjective.
