Where to lie when you live a lot (3)
I believe the answer is:
bed
'where to lie when you' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'live a lot' is the wordplay.
'live' becomes 'be' (synonyms).
'a lot' becomes 'd'.
'be'+'d'='BED'
Can you help me to learn more?
(Other definitions for bed that I've seen before include "Plot in which plants are growing" , "pit" , "One with flower, sleeper, in" , "For sleep and flowers" , "Bottom of the sea or river" .)
