Can you buy Weth?

Excuse me, I'm a bit new to the world of cryptocurrency and I was wondering if you could help me out with a question. I've been hearing a lot about this token called WETH, and I'm curious if it's something that can be purchased. If so, could you tell me a bit about the process of acquiring WETH? Is it traded on popular exchanges? Are there any specific steps I should follow to ensure a smooth transaction? I'd really appreciate any guidance you can provide. Thank you!
