Ordinary night before beam sucks up yard (8)
I believe the answer is:
everyday
'ordinary' is the definition.
(similar in meaning)
'night before beam sucks up yard' is the wordplay.
I cannot really see how this works, but
an anagram of 'yard' is 'ryda' which is located in the answer.
'night before' could be 'eve' (eve can mean the night before something) and 'eve' is present in the answer.
A single letter 'y' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for everyday that I've seen before include "familiar" , "Mundane, ordinary" , "Quotidian" , "Run-of-the-mill" , "Ordinary, for regular use" .)
