Tower in Truro 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 they are linked in a way I don't understand?
'in truro perhaps' is the wordplay.
'in' indicates a hidden word.
'ROPE' is hidden within 'truro perhaps'.
Can you help me to learn more?
(Other definitions for rope that I've seen before include "Length of material used to tie or secure things" , "Pore over a woven cord" , "Noose" , "String of pearls, say" , "Money for old . . . . Is easily earned" .)
