What is the meaning of the name Cassilyn ?

The baby name Cassilyn is a Female name , 3 syllables long and is pronounced KASS-i-lin (IPA: /ˈkæsɪlɪn/).

Cassilyn is English in Origin.

Cassilyn is a modern English given name formed by combining the Cass- element - familiar from Cassandra, Cassidy, and Cassia - with the melodic suffix -lyn/-lynn. Cass- ultimately traces to Greek Kassandra (“she who excels/shines,” the name of the Trojan prophetess), to Irish Ó Caiside (“curly‑haired”) via Cassidy, and to the aromatic cassia tree (Greek/Latin cassia). The -lyn element reflects Lynn, linked to Welsh llyn “lake, pool” and to an English surname. Together the blend suggests ideas of brightness or prophecy alongside tranquil water imagery.

Usage is recent and chiefly North American, aligning with late‑20th‑ and early‑21st‑century -lyn blends. Variants include Cassilynn, Cassilynne, Cassalyn, Kassilyn, and Kassilynn; related names are Cassandra, Cassia, Cassidy, and Lynn. Nicknames Cass and Cassie are common. Rare yet approachable, Cassilyn offers modern style with recognizable roots.
