Old soldier and mother heading up to see friend in Seville (5)
I believe the answer is:
amigo
'friend in seville' is the definition.
'amigo' can be an answer for 'friend' ('friend' in Spanish). I'm unsure of the 'in seville' bit.
'old soldier and mother heading up' is the wordplay.
'old' becomes 'o' (abbreviation).
'soldier' becomes 'GI' (GI can mean a US soldier).
'and' says to put letters next to each other.
'mother' becomes 'ma' (Ma is another word for mother or mum).
'heading up' says the letters should be written in reverse (in a down clue, letters go up).
'o'+'gi'+'ma'='ogima'
'ogima' backwards is 'AMIGO'.
'to see' acts as a link.
Can you help me to learn more?
(Other definitions for amigo that I've seen before include "Friend, comrade" , "in a foreign land, my friend?" , "buddy abroad?" , "A Spanish pal" , "friend abroad" .)
