Forms

influentialis (neuter influentiale); third-declension two-termination adjective[1][2]

Etymology

It is from Latin influentia (“influence”) + -ālis.[1][3]

Earliest recorded meaning

It is a late Medieval and Neo-Latin word.[4][2] Nicholas of Cusa, in De docta ignorantia, lists an “influential” difference beside generic, specific, local and temporal ones, and speaks of influential spirits.[2]

Semantic evolution

It belonged to astrology and natural philosophy, for the power of the heavenly bodies acting on things below:[4][1] a Polish commentary pairs the influential qualities of the heavenly bodies with the hidden virtues of stones,[1] and the DMLBS quotes it from John Dee's Monas in an astrological sense.[4] Nicholas of Cusa also has the adverb influentiāliter, by way of influence.[2] The Lexicon Bohemorum glosses it “having force”.[5]

English influential came from it, first in the astrological sense in the 1560s, then as “powerful” from the 1650s.[3]
