If Someone Has A Similar Word Trademarked

If someone has a similar word trademarked, I can’t get it at all?

Not exactly. Rather than trademark the word, though, you can design a unique logo for your business and include the name in it. Take BMW as an example. The BMW is within the logo. Or you could add a small prefix to the name, if that will do. If your name is Ravi and you want to trademark the brand ‘Winn’, you could combine create the dynamic brand R-Winn. So there are ways out. But remember that it is always good to have a unique name.
