Greek and English entering in good time for tea (4,4)
I believe the answer is:
earl grey
'tea' is the definition.
(I've seen this before)
'greek and english entering in good time' is the wordplay.
'greek' becomes 'gr'.
'and' means one lot of letters go next to another.
'english' becomes 'e' (abbreviation).
'entering' indicates putting letters inside.
'in good time' becomes 'early' (being early is arriving in good time).
'gr'+'e'='gre'
'gre' going into 'early' is 'EARL GREY'.
'for' is the link.
(Other definitions for earl grey that I've seen before include "Flavoured kind of tea" , "A type of China tea flavoured with bergamot" , "Drunk leaves" , "Noble" , "leaves much to be desired?" .)
