You may get some dinner here (3)
I believe the answer is:
inn
'you may' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'some dinner here' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'INN' can be found hidden inside 'dinner here'.
'get' is the link.
Can you help me to learn more?
(Other definitions for inn that I've seen before include "Old hostelry for travellers" , "Hostelry, tavern" , "watering-hole" , "Small hotel or country pub" , "Possibly Jamaica" .)
