It's refreshingly easy to reach (5)
I believe the answer is:
local
'reach' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for local that I've seen before include "Relating to the neighbourhood" , "Pub down the road?" , "Confined to a limited area" , "Regional, parochial" , "In the vicinity" .)
