Looking intelligent, like a Member of Parliament? (6)
I believe the answer is:
owlish
I believe this is a double definition.
'looking intelligent' is the first definition.
'like a member of parliament?' is the second definition.
(a group of owls is called a parliament )
(Other definitions for owlish that I've seen before include "solemn and wise in appearance?" , "Having appearance like wise old bird" , "Solemn, wise; like a bird" .)
