Set about foreign character that's caught inside plant (9)
I believe the answer is:
radicchio
'plant' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'set about foreign character that's caught' is the wordplay.
I cannot really understand how this works, but
'about' could be 'c' (abbreviation for 'circa') and 'c' is present in the answer.
'character' could be 'chi' (chi is a kind of character) and 'chi' is found in the answer.
'set' could be 'radio' (radio is a kind of set) and 'radio' is found within the remaining letters.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
'inside' is the link.
Can you help me to learn more?
(Other definitions for radicchio that I've seen before include "Italian chicory" , "leaves bitter taste" , "Dark-red-leaf salad plant" , "Salad ingredient" , "Variety of chicory - I hid a croc (anag)" .)
