Learn French: À force d'articuler ce son, tu vas bien le prononcer. - Through repeatedly articulating this sound, you are going to pronounce it well.

À force de translates to "by dint of" or "through repeatedly doing something". It indicates that a repeated or intense action is the cause of a result. Because it ends with the preposition de (contracted to d' before a vowel), any verb that follows it must be in the infinitive form, like articuler.

Can I use a noun after à force de instead of a verb?

Yes! While this sentence uses an infinitive, you can also use à force de with a noun to mean "by dint of something" or "due to so much something". For example, à force de pratique means "through sheer practice".

Why is the pronoun le placed right before prononcer instead of before vas?

In structures with a conjugated verb followed by an infinitive (like the near future tense here: tu vas prononcer), object pronouns usually go directly before the infinitive they belong to. Since le (meaning "it", referring to ce son) is the direct object of what you are pronouncing, it is placed right before prononcer.

Why is the adverb bien placed where it is, rather than at the end of the sentence?
