no they don't. check your dictionary, sam. eg. the house isn't there BECAUSE of a fire. it was CAUSED by an electrical short. see the difference? there is no short form for the word "because". any short form is slang, and can be spelled anyway the writer wants. don't correct someone unless you're sure you know what you are talking about!
yeah, but the word "cause" has it's own meaning that has nothing to do with the word "because". so using it as the short form just doesn't make sense. you can't put random words in where they don't belong, just because they sound similar. tbh i don't care, you can spell any way you want and use any words you want, and unlike hardtaildh08 i won't call you a f*g for it.
