Burnt material and rock on the seafront (6)
I believe the answer is:
ashore
'on the seafront' is the definition.
I can't tell whether this definition defines the answer.
'burnt material and rock' is the wordplay.
'burnt material' becomes 'ash' (I can't justify this - if you can you should believe this answer much more).
'and' means one lot of letters go next to another.
'rock' becomes 'ore' (ores are found in rocks).
'ash'+'ore'='ASHORE'
Can you help me to learn more?
(Other definitions for ashore that I've seen before include "Toward land from the sea" , "On land (as opposed to the sea)" , "Hoarse being no longer at sea" , "in port?" , "Onto land (from the water)" .)
