Pronunciation

  • IPA: /ˈkʌz.ən/[1]

Etymology

It is inherited from Middle English cosin, borrowed from Old French cosin, cusin (“nephew; kinsman; cousin”),[2][3][4] from Latin cōnsobrīnus (“mother's sister's child”),[2][3] from com- (“with, together”) and sobrīnus “cousin on the mother's side”, earlier *sosrīnos, from soror (“sister”).[2][3][5] It is related to sister.[2][3]

Earliest recorded meaning

A relative by blood or marriage: about 1225 in King Horn according to Barnhart, the early 13th century in Etymonline; it is a surname from 1160.[3][2]

Semantic evolution

The modern sense, the child of an uncle or aunt, is attested by about 1300,[2][3] but throughout Middle English the word was also used of grandchildren, godchildren and especially nephews and nieces.[2][6] A closely related thing is from the late 14th century.[2] From 1418 it was used by one sovereign addressing another.[7] First cousin and second cousin are from 1660,[7] and kindred nations, such as the British and Americans, are cousins from 1837.[7] Old English had separate words for some kinds of cousin, such as fæderan sunu “father's brother's son”.[2]
