Other forms: tipsily; tipsiest; tipsier
Use tipsy to describe a person who's just slightly drunk. If you've ever been to a wedding reception, you've probably seen a tipsy person.
Your aunt who gets a little tipsy on New Year's Eve might giggle more than usual, for example. You can also describe an inanimate object as tipsy, if it's wobbly or unstable, or even a little crooked. Tipsy comes from tip and its meaning of "slope or overturn." The old-fashioned verb tipple, to drink alcohol, came later. In the 1800's, a "tipsy cake" was one soaked in alcohol.
