Questions & Answers about Il est fatigué au point de sombrer dans l'épuisement.
Could I use à tel point de instead of au point de in this sentence?
Yes, you can use them interchangeably here. Both mean "to the point of" and express a strong consequence. à tel point de just adds a bit more emphasis on the intensity of the tiredness.
Why do we use the infinitive sombrer instead of conjugating it?
Because the subject (he) is the same for both actions: being tired and sinking into exhaustion. In French, when the subject doesn't change, we use au point de followed directly by an infinitive. If the subjects were different, you would use au point que with a conjugated verb.
What does the verb sombrer usually mean?
Is there a significant difference in meaning between being fatigué and experiencing l'épuisement?
