Etymology

Origin of proponent

First recorded in 1580–90, proponent is from the Latin word prōpōnent- (stem of prōpōnēns ). See propone, -ent

Explanation

Proponent means someone who is in favor of something. You might be a proponent of longer vacations, but your parents are proponents of a longer school year. If you’re in favor of long school vacations, you’re pro or "for" long vacations. The prefix pro- also carries the meaning of “forward,” “ahead,” or “before.” All of these senses are at work in proponent: someone who suggests (puts forward) an idea or who is in favor of an idea. A proponent proposes an idea or advocates for a proposal or a proposition.
