First, how EXACTLY do you use "と か"? I know it's used for trailing off in a sentence or something but are there any rules to how exactly to use it or can you use it with anything?

Next, if you wanted to say, for example, "I'm going to sing." than would you just say "うたいます" or something? Or is there something in particular you use for "I'm going to..."?

Also, I kinda forgot so... What is the た form exactly? How do you use it?

How exactly do you change a plain for verb into a て or た form? What are the rules?

How do you say the following in Japanese?
vvvvv
-"I don't know that word"
-"I'm sorry about -fill in the blank-"
-"How do you say that?"
-"I love that -fill in the blank-"

And one more thing, what is the best way to study? Just sit down and read a book? To just try to memorize lots of words? Or do tests and write things down and such? I always watch videos like "How I study Japanese." but they never tell you HOW exactly they study. They mainly just show you what they use to study. Any advise?

Thanks so much in advance!
