How do you spell the other word for couple?

There isn't really one "other word" for couple that has the same meaning and usage. "Couple" is pretty much the only word for two people who are romantically involved.

However, depending on the context, there are words that could be used to describe two people together:

* Pair: This is more general and could refer to any two things together, not just people.

* Duo: This is more formal and usually refers to two people who work or perform together.

* Team: This could be used for two people working together, but it suggests more collaboration and effort.

Ultimately, the best word depends on the specific situation and what you want to emphasize.
