Questions & Answers about Si tu utilises cette séquence, tu vas finir par débloquer la porte.
Why does French use the infinitive débloquer here when English says 'end up unlocking'?
In French, the phrase finir par (to end up doing something) must always be followed by an infinitive. Even though English uses an '-ing' word after 'end up', French strictly uses the infinitive verb, which is why you see débloquer.
Could I use the futur simple here and say tu finiras par débloquer instead?
Yes, you can. Both work perfectly after a present-tense si (if) clause. Tu vas finir is the futur proche (near future), which translates to 'you are going to end up' and often feels more immediate or conversational. Tu finiras means 'you will end up'.
Why use débloquer for 'unlocking' instead of déverrouiller?
Déverrouiller usually refers to physically turning a lock or bolt (un verrou). Because this sentence mentions a séquence (sequence), it likely refers to a digital keypad, a phone, or a video game puzzle. In those contexts, French speakers commonly use débloquer (to unblock or unlock digital access).
Why is it Si tu utilises (present tense) instead of Si tu vas utiliser?
This is a classic si clause rule. In French, the verb immediately following si (if) must be in the present tense to express a conditional setup, even if the action takes place in the future. You can only use the future tense for the outcome part of the sentence (tu vas finir).
