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' suggests the final letters.
'has' says to put letters next to each other.
'out' is an anagram indicator (out can mean wrong or inaccurate).
The final letter of 'evening' is 'g'.
'meal' anagrammed gives 'leam'.
'g'+'leam'='GLEAM'
'at' is the 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" .)
