Questions & Answers about À cause de cet imprévu, nous n'avons pas pu voir le décollage.
Why is pouvoir in the passé composé (n'avons pas pu) here instead of the imparfait (ne pouvions pas)?
In the passé composé, the negative form of pouvoir implies a specific failed attempt: you tried to do something but were blocked by an event on that particular occasion. If we used the imparfait (nous ne pouvions pas voir), it would just describe a general, ongoing state of inability (such as a blocked view that was already there), rather than a specific thwarted attempt.
Why use à cause de instead of parce que?
À cause de means "because of" and is always followed by a noun or pronoun (in this case, the noun phrase cet imprévu). Parce que means "because" and must be followed by a full clause with a subject and a conjugated verb. Additionally, à cause de is used for negative or neutral reasons, whereas grâce à is used when the cause is positive ("thanks to").
Imprévu looks like a verb form. How is it being used here?
It is originally the past participle of the verb prévoir (to foresee or predict). However, here it functions as a masculine noun meaning "an unforeseen event" or "a glitch". Using past participles or adjectives as nouns is very common in French, and the demonstrative adjective cet confirms it is acting as a noun here.
Why does the negation pas come before rather than after it?
