- [Instructor] The snow outside piled so high that we couldn't see thorough the window. All right. So over here, they've listed a bunch of words that sometimes people confuse or even if you read it real fast, you might read it the wrong way or you might write it the wrong way if you're doing it really quick. What we wanna say is that we couldn't see through the window but this right over here, this says thorough. Thorough means to do something completely, to do something really well, to do it thoroughly. So this right over here, we don't wanna write thorough. We wanna write through. So we look at the choices here. So we definitely wanna change it. So we're not gonna pick that. And so this is the word threw, but this sounds just like the word we want, but it's a different word. This is T-H-R-E-W. This means the past tense of throwing something, throwing a ball. He threw the ball. So that's not the type of threw that we want. This one over here, it has a lot of letters in common with through, but this doesn't spell through. This spells trough. Trough is kind of where animals might get their water from or it's sometimes used a low point in something. It is not through. So this is not through; this is trough. This right over here is the through that we want. And we want this through. This means to go through something. The snow outside, the snow outside piled so high that we couldn't see through the window, T-H-R-O-U-G-H, through the window. This type of threw, throw a ball, this is trough, and what was originally in there, that was thorough, to do something kind of really, really completely.
