These words have similar pronunciations, but very different meanings. To accept is to receive and to except is to exclude. A good way to remember the difference is that to accept something is to acquire it and to except is to cross it out with a big X.
Illusion is the more common word and usually the one you want. An illusion is a false impression, something that seems real, but isn’t. Allusion is mostly used in literary contexts.

To flounder is to flop around clumsily, like a fish on land. It can be used metaphorically for inconsistent or unproductive behavior.

When you want to give enthusiastic approval, the correct expression is “Hear, hear!” It came from the sense of hear him out! or hear this! and not from a sense having to do with here, the present location. Here, here! is an answer to “Where should I put this cupcake?”
A tortuous route might also be torturous, but the words have different meanings. Something that is torturous causes torture, while something that is tortuous is merely full of twists and turns. If a route is so tortuous that is it gives you hours of carsickness, then, yes, it is also torturous.
