Here are some other words and their nuances:
* Professor: This is the most general term for a teacher, used for all levels of education, from elementary school to university.
* Docente: This word is more formal and often used in academic settings.
* Professor particular: This refers to a private tutor.
* Mestre: While it can be used to mean "master," it can also refer to a teacher, especially in more informal contexts.
* Professor de: This is used to specify the subject the teacher teaches, for example, "Professor de português" (Portuguese teacher).
The specific translation will depend on the context. It's always helpful to provide more information about the situation, such as the level of formality or the subject being taught.
