Why is there no word in English that rhymes with Orange?

"Why is there no word in English that rhymes with Orange?"

Actually, there are a couple of words that rhyme with Orange.  There is Blorenge (a mountain in Wales) and sporange (a sac where spores are made).

If you want to get into more, you can get into "Slant Rhyming", which is what rappers do to make words that normally don't rhyme sound close enough to use in rhymes...

Then, if you want to get into really deep things, check out these words:

But I digress... 

The word "orange" is not the only word in the English language with almost nothing that rhymes with it.  There are several.  But the bigger question, the one you should be asking, is "Why is the English language so messed up?". 

Not only does it have strange words like that with nothing that rhymes, but it also has rules that seem to change on a whim.

Such as this joke that has been circulating for a long time:

But it isn't a joke, there is a reason why English is so screwed up (and getting worse), while is systematically being pushed as the future unilateral language to speak in...

Because it is a "dead language". 

I'm not referring to languages such as Latin, where nobody speaks it anymore and it is no longer changing, making it a "dead" language.  No, I'm speaking of a language that is totally devoid of any emotion when speaking it.

Almost all other languages are full of emotion, and how something is said is just as important as what is being said.  These languages are "living", they take on a life of their own just by the pattern of speech used to speak them.

But not English... It is totally devoid of life, and while some emotion is expressed while speaking it, the vast majority of it makes no difference to the ultimate meaning of what was said.

By stripping out emotion from the method of communication, you deaden the conversation.  It has become an integral part of the dumbing down of society in general.
