Hi everyone, I have been interested in this field for a while now. I can't study Etymology academically right now but I do want to study it on my own as a hobby.

How should I start? What is the step by step process? I am currently interested in scientific language the most if thats relevant. Thank you.

I mean it is probably true but I'm having a hard time understanding how it works? Commerce isn't my cup of tea. Please explain like I'm 12 :)
