year-long

UK: ˈjɪəˌlɒŋ | US: ˈjɪrˌlɔːŋ

Definition
  1. adj. lasting for or spanning a full year

Structure
year <period of 365 days>long <extended duration>
Etymology

The compound "year-long" combines "year" (from Old English "gear," meaning a cycle of seasons) and "long" (from Old English "lang," meaning extended in time or space). The fusion reflects a straightforward descriptive logic—something that lasts the duration of a year. This transparent structure is typical of English compound adjectives, where two standalone words merge to specify duration.
