Tiny piece left in accommodation for travellers (5)
I believe the answer is:
motel
'accommodation for travellers' is the definition.
(I've seen this before)
'tiny piece left' is the wordplay.
'tiny piece' becomes 'mote' (I can't justify this - if you can you should believe this answer much more).
'left' becomes 'l' (common abbreviation).
'mote'+'l'='MOTEL'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for motel that I've seen before include "Roadside establishment" , "Inn for motorists" , "Kind of hostelry for car drivers" , "Place for motorists to stay" , "Roadside hotel" .)
