dis-

Etymology

It is inherited from Middle English dis-, earlier des-,^[2][3][4] borrowed from Old French des-, also dis-, and directly borrowed from Latin dis- (“apart, asunder”),^{[5][2][3][6][4]} from Proto-Indo-European *dis- (“apart”), a variant of *dwis, from *dwō(u) (“two”).^[2][5] The primary meaning is thus in two, two ways, and it is related to Latin bis (“twice”), duo and two.^[7][6][5][8] It is cognate with Old English te-, Old Saxon ti-, Old High German zi-, German zer- and Gothic 𐌳𐌹𐍃- (dis-),^[2][5][3][9] and Barnhart and Hoad relate it to Ancient Greek διά (diá, “through”), the source of dia-.^[2][10][3] Assimilated Latin forms survive in differ, digest, dilute and divert.^[2][10]

Earliest recorded meaning

In Latin it meant apart or in different directions, as in discernō and dīmittō, the source of dismiss.^[7][6] From that came between, one by one, and a negative or reversive sense, as in disiungō, as well as an intensive force with verbs already of division.^[7][10]

Semantic evolution

In classical Latin dis- paralleled de- with much the same meaning, but Late Latin favoured it, and it passed into Old French as des- with an increasingly negative force.^[5][10][6] Middle English took many words with des- and later respelled most of them with dis-, while French often went back to dé-.^[4][5] Doublets such as disarrange and derange are the result.^[8] Hoad dates the living English prefix from the 15th century.^[10] It combines with words of any origin, making verbs of undoing (disown), verbs of removal from nouns (disbar, disfrock), and negatives of adjectives and nouns (dishonest, disunion).^[10][7][3]
