Animal look catching English learners (7)
I believe the answer is:
gazelle
'animal' is the definition.
(I've seen this before)
'look catching english learners' is the wordplay.
'look' becomes 'gaze' (gazing is a kind of looking).
'catching' means one lot of letters goes inside another.
'english' becomes 'E' (abbreviation).
'learners' becomes 'LL' (the abbreviation for learner driver written twice).
'e'+'ll'='ell'
'gaze' going around 'ell' is 'GAZELLE'.
(Other definitions for gazelle that I've seen before include "Graceful kind of antelope" , "Graceful beast" , "Thomson's antelope" , "Small graceful antelope" , "Speedy antelope" .)
