Merriam-Webster President John Morse said "w00t" reflected the growing use of numeric keyboards to type words.

"People look for self-evident numeral-letter substitutions: 0 for O; 3 for E; 7 for T; and 4 for A," he said. "This is simply a different and more efficient way of representing the alphabetical character."
