Spy alternative option for Hamlet? One's expectant (6-2-2)
I believe the answer is:
mother-to-be
'one's expectant' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'spy alternative option for hamlet?' is the wordplay.
'spy' becomes 'M' ('M' is James Bond's boss).
'alternative' becomes 'other' (I've seen this before).
'option for hamlet?' becomes 'tobe' (I've seen this in another clue).
'm'+'other'+'tobe'='MOTHER-TO-BE'
Can you help me to learn more?
(Other definitions for mother-to-be that I've seen before include "Expecting woman?" , "She's expecting" , "One expecting a baby" .)
