Came out with victory over a new ancestor (7)
I believe the answer is:
caveman
'new ancestor' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'came out with victory over a' is the wordplay.
'out with' indicates an anagram (out can mean wrong or inaccurate).
'victory' becomes 'v'.
'over' means one lot of letters go next to another (in a down clue, some letters go over others).
'a' becomes 'an'.
'came' with its letters anagrammed with 'v' makes 'cavem'.
'cavem'+'an'='CAVEMAN'
Can you help me to learn more?
(Other definitions for caveman that I've seen before include "he has primitive habits" , "Prehistoric male" , "Prehistoric person" , "old-timer?" , "Troglodyte" .)
