Celebration in Acrosses carries today’s (4)
I believe the answer is:
nina
'today's' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'celebration in acrosses carries' is the wordplay.
'carries' says the answer is hidden in the clue.
'NINA' is hidden in the letters of 'celebration in acrosses'.
Can you help me to learn more?
(Other definitions for nina that I've seen before include "- - Simone, 1933-2003, singer" , "- Simone, US singer" , "Al Hirschfeld's 'hidden' daughter" , "Girl" , "hidden crossword message" .)
