Notes for Portuguese speaking learners of English and English learners of Portuguese
There are many similarities in form and use between conditionals in Portuguese and English. Here are some differences:
• Portuguese uses the future subjunctive for first conditionals.
Se tiver boas notas, ficarei muito contente. (=If I get good marks I’ll be very happy.)
• Portuguese often uses the imperfect instead of the past simple for second conditionals.
Se exportava a tabela, precisaria de mais dados. (= If you exported the table, it would require more data.)
• Portuguese uses the imperfect subjunctive in hypothetical conditionals.
Se tivesse boas notas, ficaria muito contente. (=If I got good marks I would be very happy.)
• Portuguese uses the imperfect subjunctive plus a past participle in third conditionals.
Se tivesse contextualisado o argumento teria sido mais útil. (=If you had contextualised the argument it would have been more useful.)
