Interesting question. You can see some answers to this by going to the uspto.gov/trademarks website There are various live trademark examples of the combination of some of those first words and another dictionary word. In terms of geographical terms being combined, I'm not seeing that, but that doesn't mean that it couldn't be added.if a domain name has: come, gate, yet, mona, mai, demo, topic.... and another a dictionary word or name of a geographical place It would still be considered a trademark?
