One foreign friend or another with energy (5)
I believe the answer is:
amigo
'one foreign friend' is the definition.
(I've seen this before)
'another with energy' is the wordplay.
'another' becomes 'ami' (I've seen this in other clues).
'with' says to put letters next to each other.
'energy' becomes 'go' (go can mean energy or enthusiasm).
'ami'+'go'='AMIGO'
'or' acts as a link.
(Other definitions for amigo that I've seen before include "in a foreign land, my friend?" , "Mexican friend" , "China (in Spain's view)" , "Friend from Spain?" , "Quixote's friend" .)
