namesake

Etymology

It is formed from English name + sake (“cause, behalf”),^[2][3][4] probably shortened from phrases such as “for one’s name’s sake” and “for name sake”,^{[2][3][5][6][7]} so that a namesake was at first someone named for the sake of another person's name.^[7][8] Ayto thinks it arose from the idea of two people linked for the sake of their names,^[9] and Collins sees it as a shortening of a phrase for people connected for the name's sake.^[10] The OED compares keepsake, formed the same way.^[2][9] The first element is from Old English nama,^[6][4] and the second goes back to Old English sacu (“strife, contention, lawsuit”), from Proto-Germanic *sakō (“affair, charge, accusation”).^[9][11][12]

Earliest recorded meaning

A person or thing with the same name as another: before 1635, in Thomas Randolph's Muses Looking-glasse;^[2][7] Etymonline dates it to the 1640s.^[4]

Semantic evolution

The early sense was simply sharing a name: Johnson (1755) defined it so, quoting Sir Thomas Browne on the dog-fish and the dog in the heavens.^[13] Modern dictionaries give, as the main or special sense, a person named after another.^[7][6][10] From 1650, in Thomas Fuller, the word was also used as an adjective, “having the same name as someone or something already mentioned”, now chiefly in North America.^[2] The OED records a verb, to name after someone, from 1836, in T. C. Haliburton's Clockmaker;^[2] the Shorter Oxford calls it rare and dates it to the mid 17th century.^[3]
