However, this phrase is not commonly used in everyday conversation. It's grammatically correct, but it sounds quite formal and unusual.
To understand its meaning better, we need more context. For example, it could mean:
* "They are not together": referring to two or more people who are not in the same place or are not a unit.
* "It's not a combination": referring to two or more things that don't work well together.
* "It's not a group": referring to a collection of things that are not united.
Here are some more natural ways to express the idea of "not together" in Spanish:
* No están juntos: They are not together.
* No son un equipo: They are not a team.
* No funciona bien: It doesn't work well.
* No se combinan bien: They don't combine well.
