Portuguese grammar and vocabulary in context
Agreement and grammatical construction
Portuguese grammar choices require gender, number, verb agreement and the construction of the governing expression. Learn nouns with their articles: o problema, a análise, a viagem. An adjective or determiner must fit the actual noun phrase. Muito can be an adverb in muito interessante but agrees as a quantifier in muita gente. Do not transfer a Spanish or English pattern solely because the words look similar.
Prepositions and contractions contribute meaning. Compare em with the definite article in no and na, and a with the feminine article in à. The accent in à marks a contraction, not an optional decoration. Demonstrative contractions such as àquela involve a different second element and should be analysed explicitly. Verb government matters in gostar de, depender de and concordar com.
Tense, aspect and mood
Pretérito perfeito commonly presents a completed past occurrence; imperfeito can supply background or habitual activity, and tinha feito places an action before a past reference point. European and Brazilian uses of compound forms need context: tenho estudado is not simply interchangeable with a single completed estudei. Decide what relationship the speaker presents rather than translating an English tense mechanically.
Subjunctive forms occur in constructions involving desire, doubt, concession and purpose. Compare Espero que venha and Embora esteja cansado, continua a trabalhar. Future reference in a temporal clause can use the future subjunctive, as in Quando fizeres o trabalho, avisa-me. A personal infinitive can occur in Antes de fazeres o trabalho, lê as instruções. With regular verbs some forms coincide, but irregular fazer distinguishes fazeres from fizeres; a future meaning alone does not identify the grammatical form.
Pronouns and varieties
Clitic placement depends on construction, variety and register. In formal European Portuguese, a negative can favour preceding placement, as in Não me disse, while a simple affirmative opening can use Disse-me. Do not convert a regional preference into a universal rule for every Portuguese-speaking community. Address forms tu, você and o senhor also vary in social meaning.
Personal infinitives, subjunctives and conditional constructions should be read in context. A useful hypothetical pattern is Se estudasse mais, passaria, but an imperfect form can also have a modal interpretation in some uses. Explain the actual task’s expected register without marking every alternative as impossible. Accuracy means controlling distinctions, not memorizing inflexible shortcuts.
