The word 'twain' is an old-fashioned term that means 'two.' It used to be quite common, but it is now used mainly in specific contexts, such as literature, poetry or historical writing. For example, you can read the sentence "They parted, never to meet again in this world, for they were now twain." This means they were now two separate individuals and would not come together again. Overall, it is not commonly used in everyday conversation, but it may appear in books, articles, or formal writing.
