Etymology: "Disfavorer" is a plain formation: the noun "disfavour" (an English word meaning a lack of favour or goodwill, with the "dis-" prefix from Latin meaning "apart" or "reversal" attached to "favour") plus the suffix "-er," which marks a person who does something. A disfavorer is therefore one who withholds favour, or who shows disapproval. The word is spelled with an American "-or" ending here, while "disfavourer" uses the British "-our" spelling. Both are the same word, and the spelling difference reflects only the regional convention each form follows.

Synonyms: critic, opponent, detractor, adversary, disapprover
