Not very cerebral Lib Dem playing with words, briefly (10)
I believe the answer is:
middlebrow
'not very cerebral' is the definition.
I can't tell whether this definition defines the answer.
'lib dem playing with words briefly' is the wordplay.
'playing with' indicates anagramming the letters.
'briefly' means to remove the last letter.
'words' with its final letter taken off is 'word'.
'lib'+'dem'='libdem'
'libdem' with its letters anagrammed with 'word' makes 'MIDDLEBROW'.
Can you help me to learn more?
(Other definitions for middlebrow that I've seen before include "Not very intellectual" , "Not too intellectually stretching" , "unadventurous culturally" .)
