Rather like tea, it can be green (3)
I believe the answer is:
pea
'green' is the definition.
(pea green is a kind of green)
'rather like tea it' is the wordplay.
I cannot really see how this works, but
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is located in the answer.
The remaining letters 'pa' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'can be' acts as a link.
Can you help me to learn more?
(Other definitions for pea that I've seen before include "It grows in 23 Down" , "Climbing plant; vegetable" , "garden plant" , "Leguminous vegetable" , "Tiny stone" .)
