Standard films shown after a light feast (2,6,3)
I believe the answer is:
st davids day
'feast' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'standard films shown after a light' is the wordplay.
I cannot really see how this works, but
'standard' could be 'std' (abbreviation) and 'std' is present in the answer.
'a' is within the answer.
'light' could be 'day' (I've seen this in other clues) and 'day' is found within the answer.
The remaining letters 'vids' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for st davids day that I've seen is " big date with Myfanwy?".)
