Red is for words spelt wrong and some words that fit a lot more better. ( example would be chaging: "what old are you" for "how old are you" )
Ex. Cual = Wich
butttttt
How old are you? ~ Could be translate in to ¿Cuantos años tienes tu?
Is not What old are you, [Which is your age? ~ ¿Cual es tu edad?
What you said on What old are you? its like ¿Que tan viejo eres tu? that is not the same as How old are you? which means ur asking how old think that person he is lol.
orange is for this word that can be written like it is, but usually is written with i, only in Argentina they use it without it.
Queres in Argentina is just a bad Typo but they say it, its they way they talk.
Lime green is for where you could add a word to make the sentence sound better. (example: "when will be ready?", when will it be ready"?)
No, They "a" there is a mandatory to make the sentence have "sense"
(example: "when will be ready?", when will it be ready"?) With this you are making emphasis on something and doesn't make it generally.
Idk how to explain it but lets say like "To be ready" instead of "ready" or something like.
