Like loofahs perhaps ultimately emitting unpleasant odour (6)
I believe the answer is:
spongy
'like' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for spongy that I've seen before include "Easily squashed" , "Porous, absorbent, soft" , "prepared to absorb" , "Absorbing" .)
