Etymology: Rationalistically is a straightforward formation: the adjective "rationalistic" with the adverbial ending "-ally" attached. The adjective itself builds on "rational" plus "-istic," a suffix that marks a person or doctrine devoted to a principle, so "rationalistic" describes something governed by that devotion to reason. Adding "-ally," which descends from Old English "-līċe," turns the adjective into an adverb, meaning "in a rationalistic manner." The root "rational" comes from Latin "rationalis," from "ratio," meaning reckoning or reason, and English has used the adjective since the late Middle Ages. The "-ally" ending is the regular English way of making adverbs from adjectives ending in "-al" or "-ic," so the word's history is mostly a matter of its parts joining up.
