How To Use
Way Of Using
noun
You've seen the word 使う hopefully by now. If you have, you know it means "to use." So, the way to use something is the way of using (aka how to use). This will be a word you see when you're looking at directions for how to use something.
This uses the kun'yomi readings from the vocab words 使う and 方. So as long as you're okay with those, you can apply that knowledge over here.
