Kaelum, pronounced KAY-luhm (/keɪləm/), offers parents a little slice of celestial charm with its roots in the Latin word caelum, meaning “sky” or “heaven.” Like a gentle breeze brushing past the clouds, this name carries an airy elegance that’s rare yet approachable. In the United States, fewer than ten newborns bear the name each year—hovering around the 900th spot on the popularity charts—so it stands out without ever shouting for attention. Kaelum feels both timeless and refreshingly modern, a perfect choice for a boy destined to chart his own course. With its soft “KAY” start and lilting second syllable, it’s as if the heavens themselves whispered it into being.
