* "Te quiero" means "I love you" or "I like you a lot." It's already expressing a strong affection.
* "Tanto" means "so much" or "very much," emphasizing the intensity of "quiero."
* "Gusto" means "pleasure" or "liking." Using it after "quiero tanto" is redundant and grammatically incorrect.
Here are some correct ways to express "I love you so much" in Spanish:
* Te quiero mucho. (This is the most common and natural way to say it.)
* Te amo tanto. (This emphasizes a very strong love.)
* Te quiero con todo mi corazón. (This means "I love you with all my heart.")
Remember: Spanish grammar is a little different than English. While you might be able to say "I love you so much gusto" in English, it doesn't translate directly to Spanish.
