Species of hog from abroad (4)
I believe the answer is:
road
'species of hog from abroad' is the definition.
I can't tell whether this defines the answer.
'species of hog from abroad' is the wordplay.
'species of' becomes 'ro' (I am not sure about this - if you are sure you should believe this answer much more).
'hog' becomes 'boar' (I've seen this in another clue).
'from' indicates named letters should be taken away.
'abroad' with 'boar' removed is 'ad'.
'ro'+'ad'='ROAD'
Can you help me to learn more?
(Other definitions for road that I've seen before include "Street" , "See 10" , "Way travelled by boat" , "Way from A to B" , "Path" .)
