obstruíssem

Obstruíssem is the first-person plural imperfect subjunctive form of the verb obstruir in Portuguese. The verb obstruir means to obstruct, block, or hinder, and it is commonly used to describe actions that prevent or impede the passage or progress of something or someone. The imperfect subjunctive tense is used to express various states of unreality in the past, such as doubt, possibility, or hypothetical situations.

In the context of obstruíssem, the verb form indicates that the action of obstructing is uncertain or hypothetical in the past. For example, it might be used in a sentence like "Se nós obstruíssemos o caminho, eles não teriam passado," which translates to "If we had obstructed the path, they would not have passed." In this sentence, the use of obstruíssem suggests that the obstruction did not actually occur, but the speaker is considering the potential consequences if it had.

The conjugation of obstruir to obstruíssem follows the regular pattern for -ir verbs in the imperfect subjunctive tense. The root of the verb, obstru-, is combined with the appropriate ending for the first-person plural, -íssemos, to form obstruíssem. This conjugation is used when the subject of the sentence is "we" and the action is in the past but uncertain or hypothetical.
