Learn Portuguese (Portugal): Boa tarde, professor!

In Portuguese, descriptive words (adjectives) change to match the gender of the noun. The word for afternoon, tarde, is feminine. Therefore, we use the feminine word for good, boa. For morning (dia, which is a masculine word), we use the masculine bom.

When exactly should I start saying Boa tarde?

In Portugal, people generally switch from Bom dia to Boa tarde right after lunch (around 1:00 PM or 2:00 PM), rather than strictly at 12:00 noon. You can keep using it until it gets dark or around dinner time, when you switch to Boa noite.

Is it normal to just say "teacher" instead of using their name?

Yes, absolutely! In English, it sounds a bit unnatural to say "Good afternoon, teacher," as we usually use "Mr." or "Ms." plus a last name. In Portugal, addressing someone directly by their professional title like professor (for a man) or professora (for a woman) is the standard, polite way to speak to them.

Does professor only refer to university professors?

No, the Portuguese word professor is used for male teachers at any level of education. Whether he teaches primary school, high school, or university, he is a professor.
