Words with the letter O

The letter O is a vowel that plays a vital role in Scrabble, valued at just 1 point but incredibly versatile. It’s one of the most commonly used vowels in the English language, making it easy to incorporate into a wide range of words. Short words like go, so, to, and on are especially helpful for quick plays and creating parallel words across the board. Because of its frequency, having one or more O tiles on your rack gives you flexibility and helps in connecting with other high-scoring consonants.

Strategically, O is often used to extend existing words or to build longer ones like look, cold, bore, or storm. It’s also useful in forming plural and verb endings, such as adding -o to turn ban into bano in certain valid word lists. O pairs well with high-value consonants like J, K, and Z, helping to form big-point words like joke or zone. Even though O has a low point value, using it skillfully helps maintain rack balance and opens up opportunities for scoring in multiple directions on the board.
