Uproot underwhelming plant (3)
I believe the answer is:
elm
'plant' is the definition.
The answer is an example.
'uproot underwhelming' is the wordplay.
'ELM' is hidden within the letters.
However, I'm not sure how this is indicated.
Can you help me to learn more?
(Other definitions for elm that I've seen before include "I branch out" , "Perennial plant" , "Gray's rugged tree (Elegy)" , "Kind of 19" , "Tough timber" .)
