I left marriage finally, after former partner’s removal from home (5)
I believe the answer is:
exile
'removal from home' is the definition.
'exile' can be an answer for 'removal' (thesaurus). I am not sure about the 'from home' bit.
'i left marriage finally after former partner's' is the wordplay.
'left' becomes 'l' (common abbreviation).
'finally' suggests the final letters.
'after' means one lot of letters go next to another.
'former partner' becomes 'ex' (an ex-partner).
The final letter of 'marriage' is 'e'.
'i'+'l'+'e'='ile'
'ile' after 'ex' is 'EXILE'.
Can you help me to learn more?
(Other definitions for exile that I've seen before include "Someone sent away" , "Send abroad as punishment" , "Person banished from the home country" , "Person expelled from home country" , "Refugee" .)
