Suspend staff and phone missing husband (8)
I believe the answer is:
postpone
'suspend' is the definition.
(I know that suspend is a more specific form of the action postpone)
'staff and phone missing husband' is the wordplay.
'staff' becomes 'post' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'and' is a charade indicator (letters next to each other).
'missing' indicates named letters should be taken away.
'husband' becomes 'h' (abbreviation).
'phone' with 'h' taken out is 'pone'.
'post'+'pone'='POSTPONE'
Can you help me to learn more?
(Other definitions for postpone that I've seen before include "'Put off, delay (8)'" , "Put off, defer" , "Put off till later" , "Put off until future date" , "pigeon-hole" .)
