Note: This post is NOT a duplicate of Are "uses" and "usage" interchangeable when talking about different meanings of the same word?, which is discussing the situation of the same word. Oppose to that, this post is discussing the situation of two words.
Per Cambridge Dictionary, the word "usage" could be used as plural. Cambridge Dictionary also gives this example.
Now these two usages are syntactically distinguished as c for the first, and c for the second.
Consider this example
Spanish and Portuguese speakers often use the preposition 'en' where in English we use both 'on' and 'in'. Two separate words with very different uses in English.
which uses "uses" to convey the meaning of "the ways we use those prepositions"
Does it mean the same if "usage" was substituted for "uses"?
Two separate words with very different "usage" in English.
