A horse moves on to dry land (6)
I believe the answer is:
ashore
'to dry land' is the definition.
I can't judge whether this definition defines the answer.
'a horse moves' is the wordplay.
'moves' is an anagram indicator.
'horse' is an anagram of 'shore'.
'a'+'shore'='ASHORE'
'on' acts as a link.
Can you help me to learn more?
(Other definitions for ashore that I've seen before include "Going on land from sea" , "Hoarse (anag)" , "Hoarse being no longer at sea" , "Returned to land" , "in port?" .)
