Little chap is tired - from mining with his housemates? (6)
I believe the answer is:
sleepy
'little' is the definition.
Both the definition and answer are adjectives. Maybe there's an association between them I don't understand?
'chap is tired from mining with his housemates?' is the wordplay.
I cannot quite understand how this works, but
'chap' could be 'lee' and 'lee' is located in the answer.
The remaining letters 'spy' 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 sleepy that I've seen before include "One of the Seven Dwarfs" , "Dwarf" , "in retirement?" , "Is inactive" , "Ready to turn in" .)
