Which prefix means 'Backward'?

Con- Retro- Extra- Intra-

Correct Answer:

Retro-

Explanation:

Backward is conveyed by the prefix retro-, which comes from Latin retro meaning backward or behind. It’s used to describe motion or position toward the rear or a past state, as in retroflex (bending backward), retroperitoneal (behind the peritoneum), and retrograde (moving backward or reversing). Other prefixes have different directions: con- means with or together, extra- means outside or beyond, and intra- means within. So retro- is the one that signifies backward.
