Have you seen that strange protuberance on the tree in the park?

Yeah, I noticed it the other day; it looks really odd!

I wonder what caused that protuberance to form there.

Maybe it's some kind of fungus or a weird growth.

Root Explanation

Protuberance → It is formed from "pro-" (meaning forward) and "tuber" (from Latin "tuber", meaning swelling or lump) and the suffix "-ance" (indicating a state or quality). The word describes the state of something that is swollen or bulging forward.

Memory Tip

Think of something that is 'swelling forward' — 'pro-' means forward, and 'tuber' refers to a lump or swelling.
