Portuguese conjugation

Portuguese verbs display a high degree of inflection. A typical regular verb has over fifty different forms, expressing up to six different grammatical tenses and three moods. Two forms are peculiar to Portuguese within the Romance languages: The personal infinitive, a non-finite form which does not show tense, but is inflected for person and number. The future subjunctive, is sometimes archaic in some dialects (including peninsular) of related languages such as Spanish, but still active in Portuguese. It has also several verbal periphrases. Portuguese verbs have the following properties. Two numbers—singular, plural Three persons—first, second, third Three aspects—perfective, imperfective, progressive* Two voices—active, passive* Six morphological forms for tenses, aspects, and/or moods—present, preterite, imperfect, pluperfect, future, and conditional. Three (or four) moods—indicative, subjunctive, imperative (and conditional, according to some authors) Classes with an asterisk are entirely periphrastic. The passive voice can be constructed in two different ways. The pluperfect and the future of the indicative mood, as well as the conditional form, are often replaced with other verbal constructions or verbal periphrases in the spoken language. Conjugation is demonstrated here with the important irregular verb fazer, "to do": Periphrastic forms are as follows: The tenses correspond to: Present (presente): "I do" or "I am doing". Preterite (pretérito, or pretérito perfeito): "I did" or "I have done". Imperfect (imperfeito, or pretérito imperfeito): "I did", "I used to do", "I was doing". Pluperfect (mais-que-perfeito, or pretérito mais-que-perfeito): "I had done". Future (futuro, or futuro do presente in Brazilian Portuguese): "I will do", "I am going to do". Conditional (condicional, or futuro do pretérito in Brazilian Portuguese): "I would do". Used in some types of conditional sentences, as a form of courtesy, or as a future-in-the-past. The five non-finite forms generally correspond to: (Impersonal) infinitive (infinitivo, or infinitivo impessoal): equivalent to English "to do".
