Wine left by railway for old soldiers (7)
I believe the answer is:
cavalry
'for old soldiers' is the definition.
I can't judge whether this defines the answer.
'wine left by railway' is the wordplay.
'wine' becomes 'cava' (type of Spanish wine).
'left by' becomes 'l' (I've seen this in other clues).
'railway' becomes 'ry' (abbreviation for railway).
'cava'+'l'+'ry'='CAVALRY'
Can you help me to learn more?
(Other definitions for cavalry that I've seen before include "Horse-soldiers" , "Horse soldiers" , "Soldiers on horseback" , "Mounted soldiers" , "Mounted troops" .)
