with your mouth
Pick up the drink, put it in your mouth, swallow it.
when there is food in your mouth and you drink something the food in your mouth goes in the drink and when it is drunk by some one else it the backwash will get in that's person mouth or not.
Through their mouth
Get a drink.
Drink water
From the mouth
A cup is something you drink from with your mouth
through there mouth
Yes but you use a sponge and leave it there and it will use its long mouth to drink it.
Because they use their trunk as their mouth sometimes to when they want to drink.
Get a knife. Cut one of your veins. Put your mouth over it. Drink. :)
