Character of operations in the borders of Turkey (5)
I believe the answer is:
topsy
'character' is the definition.
I know nothing about this answer so I can't tell whether this works.
'operations in the borders of turkey' is the wordplay.
'operations' becomes 'ops' (abbreviation).
'in the' is an insertion indicator.
'borders of' means to remove the middle letters.
'turkey' with its centre taken out is 'ty'.
'ops' put into 'ty' is 'TOPSY'.
'of' is the link.
Can you help me to learn more?
(Other definitions for topsy that I've seen before include "Girl in Uncle Tom's Cabin" , "character in Stowe" .)
