Interior of pub shown with hesitation (5)
I believe the answer is:
inner
'interior' is the definition.
(I know that interior can be written as inner)
'pub shown with hesitation' is the wordplay.
I cannot quite understand how this works, but
'pub' could be 'inn' (an inn is a type of pub) and 'inn' is present in the answer.
'hesitation' could be 'er' (sound made while hesitating - um, er) and 'er' is found in the answer.
No letters remain.
This explanation may well be incorrect...
'of' acts as a link.
Can you help me to learn more?
(Other definitions for inner that I've seen before include "Close to the centre; mental" , "may not satisfy this man" , "Very private room" , "Not quite bull's-eye" , "Situated within" .)
