Watch the end! (5)
I believe the answer is:
omega
This clue might be a double definition.
'watch' is the first definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'the end' is the second definition.
(last letter of the Greek alphabet)
Can you help me to learn more?
(Other definitions for omega that I've seen before include "End of sequence" , "24th Greek letter" , ""The Alpha and the ___"" , "Greek character symbolizing resistance" , "Athenian character" .)
