- An inseparable prefix, fr. the Greek dys- hard, ill, and signifying ill, bad, hard, difficult, and the like; cf. the prefixes, Skr. dus-, Goth. tuz-, OHG. zur-, G. zer-, AS. to-, Icel. tor-, Ir. do-.
from The Century Dictionary and Cyclopedia
- An inseparable prefix in words of Greek origin, signifying ‘hard, difficult, bad, ill,’ and implying some difficulty, imperfection, inability, or privation in the act, process, or thing denoted by the word of which it forms a part.
Dis- is also now often negative, to my disgust, because of confusion with the Greek dys- (as in “dysfunctional,” a macaronic horror), but earlier meant “in different directions” (the final s happily assimilates to a following consonant).
