Looking at the question "How do I instruct my daughter to drink water from a bottle from 'up'!", I suddenly struck a question.
If that girl has drunk water by touching her lips and then if any other person comes to drink that water, what should I say?
Don't drink, it is 'used' water?
Please note that I'm not talking about germs or contamination. Here, I just want to know that someone else has already drunk from the bottle.
In Hindi, we have a word/noun for that. And, it works not only for bottle but also for food.
For instance, if I have a Kit-Kat. I licked it just once (the thing is intact, unbroken, I did not bite it) and kept it in my plate and went somewhere for a moment. My wife comes and sees the chocolate-coated wafer in the plate. She takes and is about to put it in her mouth. You, being in front of her, stops her... Whoa, that's Ruchir's. She may then reply... "Oh, okay" and keeps it back.
Kit-kat is just an international example I came up with! That's because others here may not be aware of Indian dishes that we eat with our hands. For instance, khichdi. You never know whether someone has already eaten from the plate. So, you may 'replace' khichdi with kit-kat above!
I am eager to know the native speakers' answer about this. Is there any word that describes someone has already drunk/eaten from that bottle/dishes.
J.R.'s comment about someone having mouth on it is perfect for drink/bottle. But ...food?
