Hey Reem hope this explains what you looking for VERY: As an adverb, ‘very’ is used to strengthen the meaning of an adjective or an adverb. The adjective or adverb that ‘very’ emphasizes can be followed by a noun. It was a very hot day. (emphasizing adjective ‘hot’, followed by noun ‘day’)

For me that makes sense: very is a bit formal and we use it when we want to show how much something is, and So is the informal way of this word that we can use in a regular everyday speaking, in the other hand too is so much away from these two words and we use it when we want to describe that something is more than usual that should be. Like too shiny, too shady or too small. Hope to help

Very => more than usual, So => really, truly, "So", and "very" have similar meaning and purpose.. This cake is very good. This cake is so good. This cake is really good. This cake is truly good. => => we are saying that the cake is good and we are satisfied with it. This trip is very boring. This trip is so boring. => we are saying that the trip is boring to us and that we are dissatisfied "Very, so, really, truly" just make "good" and "boring" stronger in meaning Too => more than it should, extremely It usually has a negative meaning, but not always This cake is too good = I love this cake so much that I could eat all of it This trip is too boring = I really dislike this trip and I wish I could stop it She is too good at shooting = her shooting skills are really good and better than mine. I wish I could be like her, but I know I can't. This car is too fast= car is fast but not safe
