Through vs Threw

Why the spelling matters! :3

Through : Has a soft ending that fades. You don't shape your mouth at the end of the word.

Threw: the "w" is pronounced. Your mouth retains the "u" "oo" shape at the end of the word.

English is very descriptive about how things should be pronounced, and it's easy to get confused, but often it's spelled that way for a reason. ^_^
