A version of the language almost universally agreed upon by educated English speakers around the world is called formal written English. It takes virtually the same form regardless of where it is written, in contrast to spoken English, which differs significantly between dialects, accents, and varieties of slang and of colloquial and regional expressions. Local variations in the formal written version of the language are quite limited, being restricted largely to the spelling differences between British and American English, along with a few minor differences in grammar and lexis.
