Fluent, being liberal at heart (4)
I believe the answer is:
glib
'fluent' is the definition.
(I've seen this in another clue)
'being liberal at heart' is the wordplay.
'GLIB' is hidden within the letters.
However, I am unsure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for glib that I've seen before include "Slippery in speech" , "Having only superficial plausibility" , "slick in speech" , "Fluent but evasive" , "Bush" .)
