Tower in Montenegro perhaps (4)
I believe the answer is:
rope
'tower' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'in montenegro perhaps' is the wordplay.
'in' indicates a hidden word.
'ROPE' can be found hidden inside 'montenegro perhaps'.
Can you help me to learn more?
(Other definitions for rope that I've seen before include "will it bring in easy money when old?" , "Length of material used to tie or secure things" , "Master of Suspense directed it" , "Tier" , "Hitchcock film" .)
