However, you might be thinking of:
* "Yeah": This is a more informal version of "yes" and is often used as a simple affirmation.
* "And": This is a conjunction used to connect words, phrases, or clauses. It can sometimes be used to emphasize a point, but it doesn't have a "double" meaning in the way you might be thinking.
If you can give me more context about what you're looking for, I can help you find a more specific answer. 😊
