The funny thing about this thread is, it’s supposed to be about insulting people who don’t understand definitions, but your grasp of basic grammar is terrible
First sentence

at the bolded
Next example, “words I believe is too hard”
“Words” (your subject) is plural.... yet “is” refers to a singular subject. The word “is” should be “are” since “are” refers to more than one subject.
Next example:
The word “better” should be “more easily” in your last sentence, and even that is redundant. “Comprehend” would be a fine way to end the question, but if you are comparing two things (kindergarten or adult level sources) before the comparison word, you need to ask which choice makes “more” sense.
Better is used when comparing things before you mention the choices or in the middle of the choices ie:
Which car do you like better; the red or the blue?
Do you feel better now than you did earlier?
Once you finish the question statement with comprehend, better becomes redundant.
I’m just trying to help
