If you’re a Scrabble player, you’ll be familiar with the frustration of drawing a rack full of vowels, and thinking you’ll have to settle for a six-point word. However, you might be able to pull off a 50-point bonus if you manage to use all of those vowels in just the right way. Here are five vowel-intensive words that will have you ululating* with joy:

aqueous (AH-kwee-us) adjective
Definition: Made mostly of water; watery.
Etymology: From the Latin word aqua (“water”).
Example: George looked suspiciously at the bowl of aqueous pink liquid the waiter placed in front of him, not at all convinced that it was a true Russian borscht.

onomatopoeia (ah-nuh-mah-tuh-PEE-uh) noun
Definition: A word that when pronounced makes the sound of what it describes.
Etymology: From the Greek roots onoma (“name”) and poiein (“to make”).
Example: Sizzle, hiss, zip, and buzz are all examples of onomatopoeia.

audacious (aw-DAY-shuss) adjective
Definition: Bold, confident, tending to take risks; also, impudent or disrespectful.
Etymology: From the Latin root word audax (“brave, daring”).
Example 1: Emily’s audacious decision to open her business ten years ago in the run-down warehouse district allowed her to sign a lease at a much lower cost than the other business owners who arrived after the area was gentrified.
Example 2: I don’t think Hannah looks very good in yellow either, but I would never be so audacious as to say it to her face!

facetious (fuh-SEE-shuss) adjective
Definition: Using (often inappropriate) humor while pretending to be serious; flippant.
Etymology: From the Latin word for “witty” (facetus).
Example: My son told me he really wanted to work at McDonald’s after he graduates, but I’m sure he was being facetious.

equipoise (EH-kwih-poyz) noun
Definition: Balance, equlibrium.
Etymology: From the Latin roots aequus (“even, level”) and pesum (“weight”).
Example: The Balancing Rock outcrops in Zimbabwe are amazing examples of naturally-formed granite boulders in perfect equipoise.
