therefore
UK: ˈðeəfɔː | US: ˈðerfɔːr
adv. for that reason; consequently
adv. as a logical result or inference
The word "therefore" originates from Old English þǣrfore, combining þǣr (there) and fore (for, because of). It literally meant "for that (reason)" or "because of that." Over time, it evolved into its modern usage as a conjunctive adverb indicating logical consequence, bridging cause and effect in sentences. The morpheme "there" anchors the reference to a prior statement, while "fore" (related to "for") introduces the causal relationship.
