'Word meaning' is correct or 'word meanings' is correct please suggest?
Both are correct based on context.
If you write, please see the word meaning of it---now it is an overall issue modified by a "word" an adjective in general situation and "meaning" is an uncountable noun.
Or, this word means anything.
Now, here "means" is a verb.
Or these word meanings are appalled!
By functioning, "meanings" are countable noun here.
Many nouns are countable/uncountable nouns too.
In general situation they could be uncountable, but a specific situation it could be a countable noun, clear?
We have an agreement with this co.---specific---so countable.
I have little agreement in this situation what to do! unspecific---uncountable noun,
So? Context is important in English grammar, please keep in mind.
