See how Portuguese writing, pronunciation and grammar shape what you need to notice.
Writing and sound
Portuguese uses familiar Latin letters, but nasal vowels and diphthongs give words such as mãe, não and põe their characteristic sound. Pronunciation varies substantially across the Portuguese-speaking world, even where spelling is shared.
Grammar and usage
Nouns and adjectives agree in gender and number, verbs carry extensive person and tense information, and even the infinitive can inflect for its subject. European and Brazilian usage also differ in pronoun placement and common constructions.
What to notice as a learner
Choose one variety as your speaking model, then build recognition of others through mixed audio and examples. Store phrases rather than isolated verbs so forms of address, pronoun position and regional wording stay in context.
