Brought up some past cattish behaviours (4)
I believe the answer is:
acts
'behaviours' is the definition.
The definition and answer can be both acts as well as being plural nouns.
Perhaps there's a link between them I don't understand?
'brought up some past cattish' is the wordplay.
'brought up' says the letters should be written backwards (in a down clue, letters go up).
'some' indicates a hidden word (some of the parts of the word are used).
'stca' is hidden in the letters of 'past cattish'.
'stca' backwards is 'ACTS'.
Can you help me to learn more?
(Other definitions for acts that I've seen before include "performers for revue, say?" , "individual performers in a show" , "placed before Romans?" , "appears (eight in a series may be found)" , "Pretends" .)
