Focus in college with short course (6)
I believe the answer is:
centre
'focus' is the definition.
(I know that focus can be written as centre)
'college with short course' is the wordplay.
'college with' becomes 'c' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'short' means to remove the last letter.
'course' becomes 'entree' (course of a meal).
'entree' with its final letter taken away is 'entre'.
'c'+'entre'='CENTRE'
'in' is the link.
Can you help me to learn more?
(Other definitions for centre that I've seen before include "Midpoint" , "Heart" , "- forward; - punch" , "See 24" , "Player" .)
