Archaic adverb form meaning in a strange or foreign manner; strangely or as an outsider would.
From 'fremd' (strange, foreign) + the adverb suffix '-ly.' Forms the adverbial version of the archaic adjective to describe actions or qualities in a foreign or unfamiliar way.
Fremdly is almost extinct—you almost never see it in modern writing—but it shows how English could build adverbs from any adjective, creating words for feelings of alienation and strangeness that we rarely name directly today.
