History

Etymology

From Latin efflōrēscere, present active infinitive of efflōrēscō (“to bloom, blossom; to flourish”) + -ere (suffix forming infinitives). Efflōrēscō is derived from ef- (variant of ex- (prefix meaning ‘away; out’)) + flōrēscō (“to blossom, flower; to begin to flourish or prosper”) (from flōreō (“to bloom, blossom, flower; to flourish, prosper”) (from flōs (“blossom, flower”) (ultimately from Proto-Indo-European *bhleh3- (“bloom, flower”)) + -scō (suffix forming verbs having the sense of beginning something)). By surface analysis, ef- + Latin flor- + -esce.
