Take mushroom with wild cat circling (6)
I believe the answer is:
accept
'take' is the definition.
(synonyms)
'mushroom with wild cat circling' is the wordplay.
'mushroom with' becomes 'cep' (name for Boletus edulis - an edible mushroom. I am not sure about the 'with' bit.).
'wild' indicates an anagram.
'circling' is an insertion indicator (circling can mean going around or containing).
'cat' with letters rearranged gives 'act'.
'cep' put inside 'act' is 'ACCEPT'.
Can you help me to learn more?
(Other definitions for accept that I've seen before include "one wouldn't say no to this" , "Agree or be willing to take" , "Receive voluntarily" , "Believe to be valid" , "Believe to be correct; take on" .)
