Grammar of the Portuguese language

In Portuguese grammar, nouns, adjectives, pronouns, and articles are moderately inflected: there are two genders (masculine and feminine) and two numbers (singular and plural). The case system of the ancestor language, Latin, has been lost, but personal pronouns are still declined with three main types of forms: subject, object of verb, and object of preposition. Most nouns and many adjectives can take diminutive or augmentative derivational suffixes, and most adjectives can take a so called "superlative" derivational suffix. Adjectives usually follow their respective nouns. Verbs are highly inflected: there are three tenses (past, present, future), three moods (indicative, subjunctive, imperative), three aspects (perfective, imperfective, and progressive), three voices (active, passive, reflexive), and an inflected infinitive. Most perfect and imperfect tenses are synthetic, totaling 11 conjugational paradigms, while all progressive tenses and passive constructions are periphrastic. There is also an impersonal passive construction, with the agent replaced by an indefinite pronoun. Portuguese is generally an SVO language, although SOV syntax may occur with a few object pronouns, and word order is generally not as rigid as in English. It is a null subject language, with a tendency to drop object pronouns as well, in colloquial varieties. Like Spanish, it has two main copular verbs: ser and estar. It has a number of grammatical features that distinguish it from most other Romance languages, such as a synthetic pluperfect, a future subjunctive tense, the inflected infinitive, and a present perfect with an iterative sense.

Like most Indo European languages, including English, Portuguese classifies most of its lexicon into four word classes: verbs, nouns, adjectives, and adverbs. These are "open" classes, in the sense that they readily accept new members, by coinage, borrowing, or compounding. Interjections form a smaller open class. There are also several small closed classes, such as pronouns, prepositions, articles, demonstratives, numerals, and conjunctions. A few grammatically peculiar words are difficult to categorize; these include cadê ("where is"—Braz., colloq. ), tomara ("let's hope"), oxalá ("let's hope that"), and eis ("here is"; cf. Latin ecce and French voilà). Within the four main classes there are many semi regular mechanisms that can be used to derive new words from existing words, sometimes with change of class; for example, veloz ("fast") → velocíssimo ("very fast"), medir ("to measure") → medição ("measurement"), piloto ("pilot") → pilotar ("to pilot"). Finally, there are several phrase embedding mechanisms that allow arbitrarily complex phrases to behave like nouns, adjectives, or adverbs.

Following the general Indo European pattern, the central element of almost any Portuguese clause is a verb, which may directly connect to one, two, or (rarely) three nouns (or noun like phrases), called the subject, the object (more specifically, the direct object), and the complement (more specifically, the object complement or objective complement). The most frequent order of these elements in Portuguese is subject–verb–object (SVO, as in examples (1) and (2) below), or, when a complement is present, subject–verb–object complement (SVOC — examples (3) and (4)):
(1) {A Maria}S {ama}V {o Paulo}O, "Maria loves Paulo." (2) {O pedreiro}S {construiu}V {a casa}O, "The mason has constructed the house." (3) {O presidente}S {nomeou}V o {Pedro}O {ministro}C, "The president appointed Pedro (as) minister." (4) {Ela}S {achou}V {o livro}O {uma chatice}C, "She found the book a bore." Any of the three noun elements may be omitted if it can be inferred from the context or from other syntactic clues; but many grammatical rules will still apply as if the omitted part were there. A clause will often contain a number of adverbs (or adverbial phrases) that modify the meaning of the verb; they may be inserted between the major components of the clause. Additional nouns can be connected to the verb by means of prepositions; the resulting prepositional phrases have an adverbial function. For example:
Ele carregou {sem demora} a mala {para ela} {do carro} {até a porta}, "He carried {without delay} the bag {for her} {from the car} {to the door}."
