Accommodation Theo possibly left (5)
I believe the answer is:
hotel
'accommodation' is the definition.
(type of accommodation)
'theo possibly left' is the wordplay.
'possibly' is an anagram indicator.
'left' becomes 'l' (common abbreviation).
'theo' is an anagram of 'hote'.
'hote'+'l'='HOTEL'
(Other definitions for hotel that I've seen before include "House for travellers" , "The Dorchester, say" , "guest house for a song before 8 [STATE] ..." , "Eg, Savoy, Ritz" , "Lodging establishment" .)
