Etymology: "Congratulator" is a plain formation: it takes the verb "congratulate" and adds the suffix "-or", which turns a verb into a noun for the one who performs the action. So a congratulator is simply someone who congratulates. The verb it rests on comes from Latin "congratulari", meaning to express joy together with someone, built from "con-" (with) and "gratulari" (to rejoice, from "gratus", pleasing). The "-or" ending is the same one found in words like "narrator" or "editor", and it has been used in English for centuries to name doers, though the agent noun here is a much later and rarer addition than the verb it depends on.

Synonyms: well-wisher, celebrator, complimenter, felicitator, applauder
