Origins

From Proto-Italic *-kʷe (“and”), from Proto-Indo-European *-kʷe (“and”). Cognates include Sanskrit च (ca), Ancient Greek τε (te), Faliscan -𐌂𐌖𐌄 (-cue), Proto-Germanic *-hw ( → English (thou)gh). Its alternative use as a generalizing particle "any, -every" with pronouns and adverbs may result from a shift from an earlier meaning along the lines of "as". There are also a number of words that are etymologically suffixed with this particle but that have developed specific meanings not clearly analyzable in terms of either of these senses, such as dēnique (“finally; at length”).
