Given some other situations where "tout" is used to emphasize an adverb, I thought this would be "she speaks very loudly," which was wrong. I guess this would always be taken to mean "out loud" and not "very loud"?
Yes it means strong. But in that context it would mean loudly or loud. A strong sound if you like.
Parler plus fort = to speak louder.
Parler moins fort = to speak quieter.
La télé est trop forte = The TV is too loud
I have a question, always when there is an "A" before of a verb, that implies that the person actually do or make that activity?, I mean, if I say "Await" that implies that the activity even is running?
