We possibly amble round to see a young animal (3,4)
I believe the answer is:
ewe lamb
'a young animal' is the definition.
(I've seen this in another clue)
'we possibly amble round' is the wordplay.
'possibly' is an anagram indicator.
'round' means one lot of letters goes inside another.
'amble' is an anagram of 'elamb'.
'we' going within 'elamb' is 'EWE-LAMB'.
'to see' acts as a link.
(Other definitions for ewe lamb that I've seen before include "Female baby sheep" , "precious possession" , "Young female" , "Web meal (anag.)" , "favourite member of the flock" .)
