Synonym discussion
Sense: noun/1
These words overlap, but they point to different kinds of similarity. A 'peer' is someone at your own level inside the same group, so it fits school, work, sport, and social settings: 'students learning from peers'. 'Equal' is broader and often more abstract, stressing the same value, rights, or rank rather than group membership. A 'counterpart' is usually a matching person in another company, team, or country, such as your counterpart in the Tokyo office. 'Colleague' is narrower in one way and wider in another: it is only for work, but it does not always imply equal status. Compare: 'The young lawyer impressed her peers,' 'Both partners are equals in the firm,' and 'She emailed her counterpart in Seoul.'
Etymology
Modern English 'peer' brings together two older words with different histories. The noun came into Middle English from Anglo-French 'per', meaning 'equal', and that in turn goes back to Latin 'par'. From the idea of people being equal in rank, English later developed the British title sense, since members of the peerage were treated as each other's equals. The verb is from a different line: it grew out of a Middle English verb for looking narrowly, and its form was probably shaped by 'appear'. That is why the noun and verb look identical today even though they did not start from the same root.
