Meaning & origin

Katty is a rare and modern spelling variant of Katie, a diminutive of Katherine. The name first appeared in U.S. records in 1925, but never achieved widespread popularity. Its peak year came in 2000, when it was still very uncommon. Since 2011, usage has been falling, reflecting a broader trend away from less common Katie variants. Despite its rarity, Katty offers a simple, phonetic spin on a classic name. The name has not charted in any state's top names, consistent with its national rarity.

Katty is a spelling variant of Katie, itself a diminutive of Katherine or Catherine. The name Katherine, of Greek origin (Aikaterine), became associated with the Greek word katharos, meaning 'pure', due to Christian influence. Katty emerged as a modern, phonetic respelling in the early 20th century, gaining modest use as an alternative to Katie.
