You'll need a good man to go on horseback - like this (7)
I believe the answer is:
astride
'this' is the definition.
Both the answer and definition are adverbs.
Perhaps there's a link between them I don't understand?
'you'll need a good man to go on horseback' is the wordplay.
'you'll need' becomes 'a' (I can't explain this - if you can you should give a lot more credence to this answer).
'a good man' becomes 'st' (abbreviation for saint).
'to go on horseback' becomes 'ride' (I've seen this in another clue).
'a'+'st'+'ride'='ASTRIDE'
'like' is the link.
Can you help me to learn more?
(Other definitions for astride that I've seen before include "On the back of" , "With legs apart, emitting tirades" , "Not side saddle" , "on horseback" , "Straddling (horse)" .)
