Like greatly to be in clover (4)
I believe the answer is:
love
'like greatly' is the definition.
'love' can be an answer for 'like' (loving is a kind of liking). I'm not sure about the 'greatly' bit.
'in clover' is the wordplay.
'in' says the answer is hidden in the clue.
'LOVE' is hidden within 'clover'.
'to be' acts as a link.
Can you help me to learn more?
(Other definitions for love that I've seen before include "See 22" , "God of 20 Dn" , "Nil score in 19" , "Score of zero at tennis" , "Serenade" .)
