Ray, at the end of the evening, has a meal out (5)
I believe the answer is:
gleam
'ray' is the definition.
(I've seen this before)
'the end of the evening has a meal out' is the wordplay.
'the end of' says to take the final letters.
'has' means one lot of letters go next to another.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
The last letter of 'evening' is 'g'.
'meal' with letters rearranged gives 'leam'.
'g'+'leam'='GLEAM'
'at' acts as a link.
(Other definitions for gleam that I've seen before include "Faint light; (quality) shine (in eyes)" , "Coruscate" , "Brief show of soft light" , "Flash of light" , "Ray" .)
