You may not realize that you assay things all around you every day. We all examine, analyze and try to attempt to do things every day. The reason we’re not familiar with the term is that the use of the word typically is confined to those working in labs with chemicals or metals. The closest we come to everyday life is when we take something apart to fix it like an engine.
Most of us try to write, some even daily. We all examine and analyze things before we make decisions. As you can see in the photo there aren’t many states that mine for precious and semi-precious metals. Most of this type of mining is out west whereas back east coal is king. Nonetheless, I’m confident that nobody viewing this will be adding the term to their vocabulary.
Now, if you change the vowels and come up with essey, you have a term that’s very European. It refers to furniture design and even a company by that name. Sounds like a lot of Ikea to me.
