KanjiJLPT N4
Drink

drink, smoke, take

Mnemonic

At a grand feast, the food is endless but there's nothing to drink! You start to yawn from dehydration, mouth wide open, desperately craving any beverage. Someone finally slides a cup your way — you drink it all in one gulp, and the yawn transforms into a satisfied sigh.
Additional thoughts
Picture a lavish banquet table piled high with food but not a single glass in sight. Your mouth opens in a huge yawn — the same open-mouth motion as tipping back a drink. Feast + Yawn = Drink.
Quick recall
At a feast with no drink, you yawn from thirst until someone finally hands you a cup.
