Synonym discussion

Sense: noun/1

Generation refers to people born around the same time who share cultural or historical experiences — for example, 'the post-war generation' or 'the digital generation'. Cohort is a more technical term used in research and statistics for a group of people tracked over time (e.g., 'the 1995 birth cohort'), and it does not imply shared cultural identity. Age group is broader: it covers any span of years, such as 'the 18–25 age group', and does not require a shared birth era. Peers highlights similarity in age or status within a social setting ('teenagers and their peers'), but it does not carry the historical or family meaning that generation does. When discussing how parents and children differ, use generation (generation gap). When analysing survey data by year of birth, use cohort.

Common collocations

Phrases

  • generation after generation
  • from generation to generation
  • for generations to come

Etymology

LatinOld FrenchEnglish

The word comes from Latin 'generatio' (begetting, procreation), from 'generare' (to produce, bring forth), which is built on 'genus' (birth, race, stock, family). The root 'gen-' is the same one found in 'gene', 'genetic', and 'general', all carrying the basic idea of origin, kind, or birth. The word entered English through Old French 'generacion' in the 1300s, originally referring to the act of procreation, and gradually broadened to cover groups of people born at the same time, and later to any stage of technological development.
