"Use" versus "Usage" | English Language Blog

This blog provides a clear explanation of the uses of these two words. Blogger Gabriele concludes:

In general when thinking about how these words are different it is helpful to keep in mind that the term “usage” refers to conventions or patterns and often refers to language or words and how they are used, accepted, and understood. The word “use” has a much broader meaning and is found in more contexts. In my opinion, when in doubt, use the word “use.”
