Ray embraced men awkwardly on a particular Sunday (11,3)
I believe the answer is:
remembrance day
'a particular sunday' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'ray embraced men awkwardly' is the wordplay.
'awkwardly' indicates anagramming the letters.
'ray'+'embraced'+'men'='rayembracedmen'
'rayembracedmen' with letters rearranged gives 'REMEMBRANCE DAY'.
'on' acts as a link.
Can you help me to learn more?
(Another definition for remembrance day that I've seen is " solemn occasion - with 26d".)
