Digits rung by husband to get wife, perhaps (9,6)
I believe the answer is:
telephone number
'digits rung' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'husband to get wife perhaps' is the wordplay.
I cannot quite see how this works, but
'husband' could be 'h' (abbreviation) and 'h' is found within the answer.
'get' could be 'be' ('get' can mean 'come to be') and 'be' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'by' acts as a link.
Can you help me to learn more?
(Other definitions for telephone number that I've seen before include "Very large figure" , "that may be kept in cell" .)
