Accommodation possibly let for less than a month (5)
I believe the answer is:
motel
'accommodation' is the definition.
(I've seen this before)
'possibly let for less than a month' is the wordplay.
'possibly' indicates anagramming the letters.
'for' says to put letters next to each other (I've seen this in other clues).
'less' is a deletion indicator.
'a'+'month'='amonth'
'amonth' with 'than' taken away is 'mo'.
'let' anagrammed gives 'tel'.
'tel' after 'mo' is 'MOTEL'.
(Other definitions for motel that I've seen before include "Drivers' accommodation" , "Motor lodge" , "Roadside place to stay" , "somewhere to stay the night" , "Roadside accommodation" .)
