Over in France, Louis is pronounced Lou-EE. The American way: Lou-ISS. According to [_People_](http://people.com/royals/lewis-or-louie-heres-how-to-pronounce-the-royal-babys-name/), the “s” in His Royal Highness Prince Louis of Cambridge’s royal baby name is silent, and we should all be saying his name the French way. > [](https://twitter.com/KensingtonRoyal/status/989806400380555264) The name “Louis” runs in the family. It’s Prince William’s middle name, and Prince George’s too. But his moniker likely [pays tribute](http://time.com/5257228/prince-louis-lord-mountbatten-meaning/) to Lord Mountbatten, Prince Charles’ great-uncle who was assassinated by the Irish Republican Army (IRA) in 1979\. There’s more. Prince Philip, the newborn’s great-grandfather, had a grandfather named Prince Louis of Battenberg. And there’s ties to old French royal family history too. This little Louis follows in the illustrious footsteps of other famous royals. There’s Marie Antoinette’s husband, Louis XVI, and King Louis XIV, a.k.a. the Sun King who built the Palace of Versailles. Get it right, it’s the French way. And carry on. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/5257787/royal-baby-name-louis-pronunciation/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/5257787/royal-baby-name-louis-pronunciation/"},"headline":"You're Probably Pronouncing the New Royal Baby Name Wrong","datePublished":"2018-04-27T17:05:52.000Z","dateModified":"2026-04-13T07:52:28.469Z","description":"Lou-ee or Lou-iss?","url":"https://time.com/5257787/royal-baby-name-louis-pronunciation/","keywords":["Newsfeed","royal baby","onetime"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt587139e82b6c67ec/69892ee3096a9473526a2405/prince-louis.jpeg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Ashley Hoffman","jobTitle":null,"url":"https://time.com/author/ashley-hoffman/"}],"articleSection":"","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt587139e82b6c67ec/69892ee3096a9473526a2405/prince-louis.jpeg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Prince Louis and Kate Middleton","caption":"Kate Middleton looks at her newly-born son","creditText":"Ben Stansall—AFP/Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/tag/time-section-newsfeed/","name":"Newsfeed"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/5257787/royal-baby-name-louis-pronunciation/","name":"You're Probably Pronouncing the New Royal Baby Name Wrong"}}]}] ```
