Portuguese grammar, the morphology and syntax of the Portuguese language, is similar to the grammar of most other Romance languages—especially that of Spanish, and even more so to that of Galician. It is a relatively synthetic, fusional language.

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. As in other Romance languages, there is also an impersonal passive construction, with the agent replaced by an indefinite pronoun. Portuguese is basically 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.
