Elaborated feminine form of Ariel, a Hebrew name meaning 'lion of God.'
Arielly is a lyrical elaboration of Ariel, one of the most multiply-rooted names in the Western tradition. In Hebrew, Ariel means "lion of God" — a compound of ari (lion) and el (God) — and it appears in the Hebrew Bible as both a poetic name for Jerusalem and as a figure in the Book of Ezra. In Christian angelology, Ariel became one of the named angels, an earth spirit associated with nature and elemental forces.
The name's most celebrated literary life came through Shakespeare's The Tempest (1611), in which Ariel is a sprite of air and magic — bound to the island sorcerer Prospero yet yearning for freedom — a character so memorably drawn that the name has carried that quality of airy, enchanted grace ever since. Ariel was further popularized in the English-speaking world through the poetry of Sylvia Plath, whose final collection Ariel (1965) transformed the name into a symbol of fierce female creative power. Then, in 1989, Disney's The Little Mermaid gave the name its most globally pervasive association — the red-haired, curious, boundary-crossing mermaid whose story has shaped the name's perception for an entire generation of parents.
The feminine Ariella and Arielle variants have been common in French and Hebrew-speaking communities, and Arielly extends that elaborative tradition with an additional syllable that gives the name a particularly musical, flowing quality. The -lly suffix in Arielly softens and lengthens the name without changing its essential sound, creating a version that feels simultaneously familiar and freshly individualized. It belongs to a family of elaborated feminine names — Gabrielly, Marielly — most common in Brazilian Portuguese naming culture, suggesting a possible Lusophone influence on its form.
