The words you already know

Bathroom, football, doorbell, notebook, roommate, mushroom, barefoot, goodness, doorstep, and smoothly all fit the pattern, and you've probably typed or said most of these this week without thinking twice. If a word list you're looking at is full of things like oogonium or zootypic, that's dictionary trivia, not something you'll ever actually need.

Why OO shows up so often at exactly eight letters

Look closely at that first list and a pattern jumps out fast. Doorbell is door plus bell. Football is foot plus ball. Roommate is room plus mate. Notebook is note plus book. Mushroom is mush plus room. A big chunk of eight letter OO words aren't really one word at all. They're two shorter words stuck together, and English just happens to have a lot of short, common words that start or end with OO, like door, foot, room, book, and moon. Put two four letter words like that side by side and you land right at eight letters. That's the real reason this pattern shows up so much, and it's also why these words feel so familiar even though nobody points this out.

The one to remember for Scrabble

If you're playing Scrabble or Words With Friends, the word worth knowing is schmoozy. It's eight letters, it contains OO, and it's the highest scoring OO word in the whole Scrabble dictionary at 27 points before any bonus tiles. Most of the other big scorers with OO, like bazooka and woozily, are actually seven letters, so schmoozy pretty much owns the eight letter spot on its own.

If none of these fit your board

Sometimes the word you need isn't on this shortlist, especially if you already have a few letters locked in on the board. WordsGallery's word finder can pull the complete list of eight letter OO words and filter it by the other letters you're holding, which is a lot faster than scrolling through a few hundred entries by hand.
