Terry’s phone’s cut! (3)
I believe the answer is:
tel
'terry's' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see a link between them that I can't see?
'phone's cut' is the wordplay.
'phone's' becomes 'tels'.
'cut' means to remove the last letter.
'tels' with its final letter removed is 'TEL'.
Can you help me to learn more?
(Other definitions for tel that I've seen before include "Ancient mound in Arab lands" , "Ancient mound in Middle East" , "Small number" , "-- Aviv; old mound" , "Phone number (abbrev.)" .)
