Animal look catching European students (7)
I believe the answer is:
gazelle
'animal' is the definition.
(I've seen this before)
'look catching european students' is the wordplay.
'look' becomes 'gaze' (gazing is a kind of looking).
'catching' indicates putting letters inside.
'european' becomes 'E' (abbreviation e.g. EU).
'students' becomes 'LL' (two abbreviations for learner).
'e'+'ll'='ell'
'gaze' going around 'ell' is 'GAZELLE'.
(Other definitions for gazelle that I've seen before include "A amall graceful Antelope" , "Animal" , "Graceful antelope of Africa and Asia" , "Graceful kind of antelope" , "Small graceful antelope" .)
