End call in a telephone box? (9)
I believe the answer is:
terminate
'end' is the definition.
(synonyms)
'call in a telephone box?' is the wordplay.
'call' becomes 'term' (term can mean to call something by a name).
'a telephone box?' becomes 'ate' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'term'+'in'+'ate'='TERMINATE'
Can you help me to learn more?
(Other definitions for terminate that I've seen before include "Cut short" , "Stop" , "Finalise" , "Put an end to, discontinue" , "Kill off" .)
