B2 (Upper Intermediate)Lesson 7: Normative Essentials
Punctuation and orthography shape readability and register. A few high-value rules make a major difference in written Portuguese.
Comma use follows structure
Never split subject and verb with a comma
High-frequency spelling contrasts deserve automatic control
These rules sit on the surface of the text, so readers notice them instantly. Good punctuation and orthography make writing easier to trust and easier to follow.

Use commas to mark vocative, apposition, many fronted subordinate clauses, and some longer adjuncts.
Do not separate subject and verb with a comma.
Question marks, exclamation marks, colons, and quotation punctuation follow ordinary discourse structure, not just emotion.
Orthography matters in contrasts such as "porque / por que / por quê / porquê".
Language names like "português" are usually lower-case in Portuguese, and many compounds like "guarda-chuva" depend on fixed spelling.
Punctuation is partly syntactic and partly rhetorical; structure comes first.
Orthographic accuracy is especially visible in emails, essays, formal posts, and public writing.
| Portuguese | Meaning |
|---|---|
| Pedro, fecha a porta. | Pedro, close the door. |
| Ana, minha colega, chegou. | Ana, my colleague, arrived. |
| Quando ele chegou, eu já tinha saído. | When he arrived, I had already left. |
| Por que você saiu cedo? | Why did you leave early? |
| Não sei por quê. | I don't know why. |
| O português do Brasil varia muito. | Brazilian Portuguese varies a lot. |
Comma choices can vary for rhythm in literary prose, but core structural rules remain.
Orthographic reforms and fixed compounds must be learned lexically where necessary.
