Survive abroad with pounds I have (7)
I believe the answer is:
outlive
'survive' is the definition.
(synonyms)
'abroad with pounds i have' is the wordplay.
'abroad' becomes 'out' (abroad can mean away or out).
'with' says to put letters next to each other.
'pounds' becomes 'l' (abbreviation e.g. Lsd - pounds, shillings, pence).
'i have' becomes 'I've' (contraction of 'I have').
'out'+'l'+'ive'='OUTLIVE'
(Other definitions for outlive that I've seen before include "Go on longer than" , "Survive longer than" , "Die after" , "Survive beyond (another)" , "weather" .)
