How do you say Houston in Scottish Gaelic?

There isn't a direct translation of "Houston" in Scottish Gaelic. Scottish Gaelic doesn't have a system for directly transliterating foreign place names like English does. You would need to either:

* Use the English word: Simply say "Houston" – many loanwords are used in Gaelic.

* Describe it: If you need to describe the place in Gaelic, you would have to say something like "A' bhaile mòr ann an Texas" (The big town in Texas). This is a descriptive phrase, not a true translation.

Therefore, there's no single, definitive Gaelic equivalent for "Houston".
