Look around European lakes for animal (7)
I believe the answer is:
gazelle
'for animal' is the definition.
(I've seen this before)
'look around european lakes' is the wordplay.
'look' becomes 'gaze' (gaze is a kind of look).
'around' says the letters should be written backwards.
'european' becomes 'E' (abbreviation e.g. EU).
'lakes' becomes 'LL' (a geographical abbreviation for lake written twice).
'e'+'ll'='ell'
'ell' written backwards gives 'lle'.
'gaze'+'lle'='GAZELLE'
(Other definitions for gazelle that I've seen before include "Graceful antelope of Africa and Asia" , "Slender antelope" , "Small graceful antelope" , "''both / beautiful, one a ...'' (Yeats)" , "Graceful kind of antelope" .)
