Neil and I together wake late! (3,2)
I believe the answer is:
lie in
'together wake late' is the definition.
I can't judge whether this definition defines the answer.
'neil and i' is the wordplay.
I cannot quite see how this works, but
'and' could be 'n' (common abbreviation for 'and') and 'n' is located in the answer.
'i' is within the answer.
The remaining letters 'lei' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for lie in that I've seen before include "Extended snooze" , "Stay in bed, be a lazybones" , "Rise late" , "Protracted stay in bed" , "An extra spell in bed" .)
