A French comic entertainer? (4)
I believe the answer is:
dawn
'a french' is the definition.
(comedian Dawn French)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for dawn that I've seen before include "Early morning sing-song?" , "Threshold" , "Daybreak" , "Sunrise" , "Aurora was its goddess" .)
