- 1聊天、簡訊裡用 2 來寫 to 或 too（諧音 two）。作文、考試不要用。
In texts and very casual emails, people write 2 for to or too, because those words sound like the number two. You might see “going 2 school” or “me 2”. It is a shortcut, not a new word, and it does not tell you which spelling they meant — you have to read the rest of the line. Though actually, many people mix this with other number tricks in the same message, which is why it looks messy to anyone who is not in the chat. Never use it in school work, job mail, or anything a teacher will mark.
在簡訊和很隨意的郵件裡，人們會用 2 來寫 to 或 too，因為發音像數字 two，例如 going 2 school（去學校）、me 2（我也是）。這是縮寫，不是新字，也不會告訴你到底是 to 還是 too，要看整句的上下文。很多人會在同一則訊息裡混用其他數字寫法，所以不在聊天裡的人看起來會很亂。作業、工作郵件，或老師會批改的東西，都不要用這個寫法。
組成The digit 2, used because two sounds like to and too. It does not split into smaller pieces.
