Basic accommodation's one good toilet? (5)
I believe the answer is:
igloo
'basic accommodation's' is the definition.
'igloo' can be an answer for 'accommodation's' (I have seen 'cold accommodation' mean 'igloo' so perhaps 'accommodation' could also mean 'igloo'). I'm unsure of the 'basic' bit.
'one good toilet?' is the wordplay.
'one' becomes 'i' (Roman numeral).
'good' becomes 'g' (abbreviation).
'toilet?' becomes 'loo' (loo can informally mean a toilet).
'i'+'g'+'loo'='IGLOO'
Can you help me to learn more?
(Other definitions for igloo that I've seen before include "Arctic dwelling" , "Stacked blocks" , "basic dwelling" , "Inuit building" , "native dwelling" .)
