À vs De using Infinitives
Is there a pattern as to how I can n’identifie which verbs take de or a or nothing with them when using a later verb in the infinitive? I’m trying to study for a test but I can’t seem to find any device that would allow me to memorize then rather than just brute-forcing it and memorizing every individual verb. Is there any sort of pattern I should look for?
"À" is used when you want to describe an action based on a certain object or activity. This means that "à" must be used after an object in the sentence, and can even be used to describe other infinitives.

These tests are hard to pass.
Otherwise, "de" is used when you want to desbribe an action with the "dummy subject," "il." I would say these are easier to use and more flexible than using "à," simply because it always follows the same form, but this is just my opinion.
Format: Il est [adjectif] de [verbe]-[objet (in)direct]/[adverbe].

Note that you cannot use the "de" construction of infinitives when you want to use "il" as the subject pronoun for male people. In the scenarios, you must still use "à."
