Does old locomotive press a mount? (4,5)
I believe the answer is:
iron horse
'does old locomotive' is the definition.
I can't tell whether this defines the answer.
'press a mount?' is the wordplay.
'press' becomes 'iron' (ironing is a kind of pressing).
'a mount?' becomes 'horse' (mount is a kind of horse).
'iron'+'horse'='IRON HORSE'
Can you help me to learn more?
(Other definitions for iron horse that I've seen before include "one's gone off the rails" , "Steam locomotive" , "Old name for locomotive" , "loco" , "People made tracks for this!" .)
