What does the prefix Osmo- indicate?

• A. Odor
• B. In front of, before
• C. Shaped like a top
• D. Twitch or pull

Answer: (A)

Osmo- refers to odor or smell. It comes from the Greek osme, meaning a smell. So any term using this prefix is signaling something related to scent, not time, position, or shape. The other ideas—front of, top-shaped, or twitch/pull—come from different roots and don’t match this prefix.
