Urge to bed emoji? (8)
I believe the answer is:
eggplant
'emoji?' is the definition.
I can't judge whether this defines the answer.
'urge to bed' is the wordplay.
'urge' becomes 'egg' (as in egging someone on).
'to' is a charade indicator (letters next to each other).
'bed' becomes 'plant' (I can't explain this - if you can you should give a lot more credence to this answer).
'egg'+'plant'='EGGPLANT'
Can you help me to learn more?
(Other definitions for eggplant that I've seen before include "Vegetable" , "It's also called aubergine" , "What goes into moussaka" , "Its fruit is aubergine" , "US name for aubergine" .)
