Newspeak was founded on the English language as we now know it, though many Newspeak sentences, even when not containing newly-created words, would be barely intelligible to an English-speaker of our own day. Newspeak words were divided into three distinct classes, known as the A vocabulary, the B vocabulary (also called compound words), and the C vocabulary. It will be simpler to discuss each class separately, but the grammatical peculiarities of the language can be dealt with in the section devoted to the A vocabulary, since the same rules held good for all three categories.
