The Letter Q

My random thoughts on the letter Q, and a theory about it: 

Q always has to have a U after it...or does it?... 

If you say a word beginning with Q, let's say quality. Say it slowly and pay attention to the Q and the U. It sounds sorta like a KW doesn't it? 

Now, there are some instances in which a U makes a W sound. The only example I can think of right now, is the name Eduardo. The u is what makes the W sound. 

So if someone were to take the Q out of the word quality, or any other word with a Qu that makes a KW sound, and replace it with another constinent like a D or a T, would the U still make a W sound? It most certainly could! 

One more thing: think of the word "Quesadilla" it's a spanish word, and the U is silent. There, the U is still used, but the Q makes a K sound. Same thing with the word qui, which means "where" in french. And alot of other french words now I think of it, in French they don't use the English Q = KW sound standard at all. 

But this isn't just for french.  Some English words too, like "unique" and "technique" and the most infamous "queue" are examples of when the letter U simply refuses to do it's job of making the Q a KW. 

And as for the silent E at the end, E'S at the ends of words are often used to make vowels make the sound of their letter name, for example, "ay" for A "Ee" for E and "Oh" for O. Maybe the E'S are doing the same thing for the Q in this situation, making it show it's true colors...which brings me too...wait for it...wait for it………

What if the actual sound of the letter Q is actually a K??!! 

It makes a lot of sense! 

What if the first inventors of the english language knew this, but didn't want to admit there was a third letter that made a K sound so said it had to make a qu sound but had to have a U after it???? 

Let me know in the comments what you think of this theory!
