conditional is also called past future futuro do pretérito, as it describes both conjectures that would occur given a certain condition and actions that were to take place in the future, from a past perspective. When the conditional has the former purpose, it imperatively comes along with a conditional subordinate clause in the past subjunctive.

The conditional is also one of the two Portuguese tenses that demand mesoclisis when proclisis is forbidden since enclisis is always considered ungrammatical.
