influential

the word "influential" is a tributary of the river of words stemming from the latin verb influere, meaning "to flow into". this verb itself is composed of in- (into) and fluere (to flow). the original, literal sense was astrological, describing an ethereal fluid believed to stream from the stars and flow into human affairs, thus affecting destiny. over time, this concrete notion of a flowing force was abstracted into the general concept of a power that shapes events or sways opinions. the suffix -ential was later appended to the present participle form (influens) to create the adjective, characterizing a person or thing that possesses this flowing, shaping power.

Structure: in (into) + flu (flow) + ential (adjective suffix) - in: latin origin, meaning "into, in, on". serves as an intensive prefix in this compound. - flu: latin origin, from fluere (to flow). serves as the core root conveying the sense of "flow". - ential: latin origin, a compound suffix combining -ent- (present participle/adjectival) + -ial (relating to), forming an adjective meaning "characterized by or pertaining to".
