B2 (Upper Intermediate)Lesson 8: 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

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.
| Step | Rule |
| 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.
