Horse running along bank (5)
I believe the answer is:
shore
'along bank' is the definition.
'shore' can be an answer for 'bank' (thesaurus). I'm not sure about the 'along' bit.
'horse running' is the wordplay.
'running' indicates anagramming the letters (the letters run around to different places).
'horse' anagrammed gives 'SHORE'.
Can you help me to learn more?
(Other definitions for shore that I've seen before include "Beam" , "Land beside sea, lake" , "Land along the edge of sea or lake" , "support being only temporary?" , "Country" .)
