Dislike removing a brand (7)
I believe the answer is:
version
'brand' is the definition.
The definition and answer can be both related to thinking as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'dislike removing a' is the wordplay.
'dislike' becomes 'aversion' (aversion is a kind of dislike).
'removing' indicates named letters should be taken away.
'aversion' with 'a' taken away is 'VERSION'.
Can you help me to learn more?
(Other definitions for version that I've seen before include "See 24" , "Interpretation, account" , "Translation - personal account" , "Sort" , "Model" .)
