Old woman carrying in a simple wind instrument (7)
I believe the answer is:
ocarina
'a simple wind instrument' is the definition.
(I've seen this before)
'old woman carrying in' is the wordplay.
'old' becomes 'o' (abbreviation as in OT - Old Testament).
'woman' becomes 'cara' ().
'carrying' is an insertion indicator.
'cara' enclosing 'in' is 'carina'.
'o'+'carina'='OCARINA'
(Other definitions for ocarina that I've seen before include "Inca oar made into a musical instrument" , "Wind instrument with a mouthpiece and finger holes" , "toy instrument" , "Terracotta wind instrument" , "Toy flute" .)
