I'm trying to understand where the adverb goes when it modifies an infinitive in a phrase with complements and prepositions.
In a sentence such as il ne suffit pas de le faire where I want to modify le faire with an adverb such as tout simplement to even just simplement, I would be inclined to put the adverb after the infinitive. However, my understanding of rules governing adverb use has always been somewhat rudimentary and I'd like to get a better grasp on why adverbs go where they do, especially when they are modifying unconjugated verbs.
If anyone can help me to understand these rules I'd really appreciate it. Cheers!
