An escort is arranged for one who has gone before (8)
I believe the answer is:
ancestor
'an escort is arranged for one who has gone before' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'an escort is arranged for one' is the wordplay.
'is arranged' indicates an anagram (letters rearranged).
'for' says to put letters next to each other (I've seen this in other clues).
'one' becomes 'an' (an apple is one apple).
'escort' with letters rearranged gives 'cestor'.
'cestor' after 'an' is 'ANCESTOR'.
Can you help me to learn more?
(Other definitions for ancestor that I've seen before include "Forefather" , "Adam was our first one" , "Enactors (anag)" , "one is up a tree" , "descent comes from one" .)
