## AI Etymology
Coetaneous comes from Late Latin coaetāneus 'of the same age', from co- 'together' + aetās 'age', from aevum 'age, lifetime'. The historical trail runs through coaetāneus in Latin, aetās in Latin, and aevum in Latin. Morphologically, coetaneous is transparent: it draws on Late Latin coaetāneus 'of the same age', from co- 'together' + aetās 'age', from aevum 'age, lifetime'. Used as an adjective, coetaneous now means "of the same age or duration; contemporary", so the present definition can be read against the older forms and meanings. The same lexical family is also visible in related forms such as coeval and eternal. The result is a borrowed or transmitted form whose modern spelling carries a compact record of its route into English.
