The English translation of the French verb désenvaser is “to unclog” or “to unclog a drain.” It is pronounced as “day-zanh-vah-zay” in its infinitive form.

The word désenvaser is a combination of the prefix dés- (meaning “undo” or “remove”) and the verb envaser (meaning “to clog” or “to fill with mud”). Therefore, the literal meaning of désenvaser is “to remove the clog.”

In everyday French, désenvaser is most often used in the Conditionnel Passé tense to express a hypothetical or unreal action that would have happened in the past if certain conditions had been met. It is formed by conjugating the auxiliary verb avoir in the Conditionnel Présent tense, followed by the past participle of désenvaser (désenvasé).

Désenvaser – About the French Conditionnel Passé (Conditional Past) Tense

The French “Conditionnel Passé” is a compound tense used to express hypothetical or unreal actions in the past. It is formed by combining the conditional of the auxiliary verb “avoir” or “être” and the past participle of the main verb.

NOTE: To take a deep dive into all the French tenses then see my article on Mastering French Tense Conjugation.

Formation

Start with the conditional of the auxiliary verb: For most verbs, use “aurais” (for “avoir”) or “serais” (for “être”) as the conditional form. 

With “avoir”: j’aurais, tu aurais, il/elle/on aurait, nous aurions, vous auriez, ils/elles auraient. 
With “être”: je serais, tu serais, il/elle/on serait, nous serions, vous seriez, ils/elles seraient. 

Add the past participle of the main verb to this conditional form. 
For example, if you want to say “I would have done,” you would use “j’aurais fait.” If you want to say “She would have gone,” you would use “elle serait allée.”

Common Everyday Usage Patterns

You might use the Conditionnel Passé alongside indicative past tenses like the passé composé to contrast hypothetical and real past events. Il est venu hier, mais s’il avait pu, il serait venu la semaine dernière. (He came yesterday, but if he could have, he would have come last week.) 

Conditional Future
