Flat accommodation for one letter? (8)
I believe the answer is:
envelope
'flat accommodation' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'one letter?' is the wordplay.
I cannot really understand how this works, but
'one' could be 'o' (I've seen this in other clues) and 'o' is found within the answer.
'letter?' could be 'pe' (pe is a kind of letter of the alphabet) and 'pe' is located in the answer.
This explanation may well be incorrect...
'for' is the link.
Can you help me to learn more?
(Other definitions for envelope that I've seen before include "Wrapper for 31ac" , "Cover for letter" , "Container for pager" , "skin?" , "Paper wrapper" .)
