Urge to bed emoji? (8)
I believe the answer is:
eggplant
'emoji?' is the definition.
I can't judge whether this definition defines the answer.
'urge to bed' is the wordplay.
'urge' becomes 'egg' (as in egging someone on).
'to' says to put letters next to each other.
'bed' becomes 'plant' (I am not sure about this - if you are sure you should believe this answer much more).
'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" .)
