Many wild mobs are apt to be hairy (5)
I believe the answer is:
combs
'apt to be hairy' is the definition.
I can't tell whether this defines the answer.
'many wild mobs' is the wordplay.
'many' becomes 'c' (C is the Roman numeral for 100).
'wild' is an anagram indicator.
'mobs' is an anagram of 'ombs'.
'c'+'ombs'='COMBS'
'are' acts as a link.
Can you help me to learn more?
(Other definitions for combs that I've seen before include "Crests" , "Searches thoroughly" .)
