Rily

Rily is a masculine name that appears to be a variant spelling of Riley, which originated as an Irish surname derived from the Gaelic "Ó Raghailligh" meaning "descendant of Raghallach." This particular spelling is significantly less common than Riley, which has become popular as a first name for both boys and girls in recent decades. The name has a friendly, approachable quality with its short two-syllable structure. Rily emerged primarily in the United States during the late 20th century when alternative spellings became more common. While lacking the historical usage of Riley, this variant maintains the same casual, energetic appeal while offering a slightly more distinctive spelling.

Rily is also given to girls.

Pronounced RY-lee.
