Which prefix means difficult or bad?

Dys- Tachy- Neo- Ex-

Correct Answer:

Dys-

Explanation:

Dys- is the prefix that signals something is difficult, bad, or abnormal. It comes from Greek and is used to indicate negative or impaired conditions, as in dysuria (painful or difficult urination), dysplasia (abnormal development), and dysfunction (impaired function). The other prefixes have different meanings: tachy- means fast; neo- means new; ex- means out of, away from, or former. So this prefix best conveys the idea of something being troublesome or abnormal.
