proponent

Etymology

It is borrowed from Latin prōpōnēns (“putting forth; one who proposes”),^{[2][3][4][5][6]} the present participle of prōpōnō (“to put forth, set forth”),^[3][5][7][6] from prō- and pōnō (“to put, place”).^[2] Barnhart and Etymonline think it was in part also formed in English from the verb propone, to propose (from 1400), with the suffix -ent.^[5][7] The same Latin verb gave propound and propose.^[7][6][3] The sense of a lay preacher in the colonies of the Netherlands follows Dutch proponent (“lay preacher”).^[2]

Earliest recorded meaning

A person who puts forward a proposition or argument: 1588, in Abraham Fraunce's Lawiers Logike.^[2][5][7][4]

Semantic evolution

The word began in logic and law, for the one who sets out a proposition or argument;^[2][7] Johnson (1755) still defined it simply as one who makes a proposal, quoting Dryden.^[8] In later use it came to mean, more generally, someone in favour of a theory, policy or cause, a supporter or advocate,^[2][4] and Merriam-Webster sets it against opponent.^[4] In law it also names the person who asks for a will to be admitted to probate.^[9][4] In the 19th century it was used in Ceylon and other Dutch colonies for a man licensed to carry out certain duties of the Dutch Reformed Church.^[2] The adjective, putting forward a case, chiefly in law, is recorded from before 1677.^[2][7]
