A growth maybe considered ugly (4,3)
I believe the answer is:
wart hog
'considered ugly' is the definition.
I can't tell whether this defines the answer.
'a growth maybe' is the wordplay.
'maybe' indicates anagramming the letters.
'a'+'growth'='agrowth'
'agrowth' with letters rearranged gives 'WART-HOG'.
Can you help me to learn more?
(Other definitions for wart hog that I've seen before include "(Ugly) African wild pig" , "Wild boar of Africa" , "A growth (anag) -- African animal" .)
