Shown in by the old woman inside (7)
I believe the answer is:
ushered
'shown in' is the definition.
'ushered' can be an answer for 'shown' ('usher' can be a synonym of 'show'). I am unsure of the 'in' bit.
'the old woman inside' is the wordplay.
'the old' becomes 'used' (as in used or second-hand items).
'woman' becomes 'her' (her refers to a woman).
'inside' means one lot of letters goes inside another.
'used' placed around 'her' is 'USHERED'.
'by' acts as a link.
Can you help me to learn more?
(Other definitions for ushered that I've seen before include "Showed people to seats as in cinemas or theatre" , "Showed to a seat" , "Led" , "Escorted" , "Conducted" .)
