The name Liam was the second-most popular baby boy name of the decade, with 152,994 baby Liams being born between 2010 and 2018, according to the Social Security Administration. The name's popularity is relatively new, as Liam has only been a top-five name since 2013, per the Social Security Administration. Basically, as Liam hasn't been popular for long, the years that it has been popular have been pretty outstanding for the name. More and more parents have used Liam as a baby boy name for a multitude of reasons, but the name's meaning is what's really interesting.
Really, Liam has risen in popularity pretty quickly, but the name has a fairly old-fashioned meaning and background. According to Behind the Name, Liam comes from William, which means "will helmet," composed of the elements wil, meaning "will, desire" and helm, meaning "helmet, protection." As the website reported, William has been a popular name for centuries, as plenty of royals and notable figures have shared the same name. Still, Liam is different than William, and, according to The Bump, is far more popular.
