A lot vs. Alot: 9 Grammatical Pitfalls
Old English fyrmest "earliest, first, most prominent," from Proto-Germanic *formo- (related to Old English fruma "beginning"), superlative of the root of fore + additional superlative suffix -est. Cf. -most, and cf. also Old Frisian formest, Gothic frumists. Altered on the assumption that it is a compound of fore and most.
