Five English students getting the Morning Star (5)
I believe the answer is:
venus
'the morning star' is the definition.
(I've seen this before)
'five english students getting' is the wordplay.
'five' becomes 'v' (roman numeral).
'english' becomes 'e' (abbreviation).
'students' becomes 'nus' (I've seen this in other clues).
'getting' means one lot of letters go next to another.
'v'+'e'+'nus'='VENUS'
(Other definitions for venus that I've seen before include "not really a star" , "The embodiment of Love" , "Next planet in" , "One of the planets" , "Heavenly body" .)
