distaste (n.)

word-forming element of Latin origin meaning 1. "lack of, not" (as in dishonest); 2. "opposite of, do the opposite of" (as in disallow); 3. "apart, away" (as in discard), from Old French des- or directly from Latin dis- "apart, asunder, in a different direction, between," figuratively "not, un-," also "exceedingly, utterly." Assimilated as dif- before -f- and to di- before most voiced consonants.

The Latin prefix is from PIE *dis- "apart, asunder" (source also of Old English te-, Old Saxon ti-, Old High German ze-, German zer-). The PIE root is a secondary form of *dwis- and thus is related to Latin bis "twice" (originally *dvis) and to duo, on notion of "two ways, in twain" (hence "apart, asunder").

In classical Latin, dis- paralleled de- and had much the same meaning, but in Late Latin dis- came to be the favored form and this passed into Old French as des-, the form used for compound words formed in Old French, where it increasingly had a privative sense ("not"). In English, many of these words eventually were altered back to dis-, while in French many have been altered back to de-. The usual confusion prevails.

As a living prefix in English, it reverses or negatives what it is affixed to. Sometimes, as in Italian, it is reduced to s- (as in spend, splay, sport, sdain for disdain, and the surnames Spencer and Spence).

early 14c., "act of tasting," from Old French tast "sense of touch" (Modern French tât), from taster (see taste (v.)). From late 14c. as "a small portion given;" also "faculty or sense by which the flavor of a thing is discerned;" also "savor, sapidity, flavor."

Meaning "aesthetic judgment, faculty of discerning and appreciating what is excellent" is first attested 1670s (compare French goût, German geschmack, Russian vkus, etc.).

Of all the five senses, 'taste' is the one most closely associated with fine discrimination, hence the familiar secondary uses of words for 'taste, good taste' with reference to aesthetic appreciation. [Buck]

Taste is active, deciding, choosing, changing, arranging, etc.; sensibility is passive, the power to feel, susceptibility of impression, as from the beautiful. [Century Dictionary]

"unpleasant or disgusting to the taste," c. 1600, from distaste + -ful. Related: Distastefully; distastefulness.
