Loft found in Muscat ticket office (5)
I believe the answer is:
attic
'loft' is the definition.
(synonyms)
'in muscat ticket office' is the wordplay.
'in' indicates a hidden word.
'ATTIC' is hidden in the letters of 'muscat ticket office'.
'found' acts as a link.
(Other definitions for attic that I've seen before include "Top storey" , "Room at the top of a house" , "where high-ups are found?" , "Classically elegant" , "cockloft" .)
