Like a former presidential beard, possibly? (5)
I believe the answer is:
bushy
'like' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for bushy that I've seen before include "Thick, unkempt" , "Hairy" .)
