About Mermaid names
Mermaid names should sound like water and song — long vowels, soft sibilants, and a sense of something half-heard from a long way off. This generator draws on global mermaid and water-spirit traditions, from the Celtic selkie to the Greek siren to the Southeast Asian Suvannamaccha, describing each with respect and without copying any single name from any source. Use the subtypes to move between reef mermaids of sunlit shallows, deep-sea mermaids of the abyss, siren mermaids of dangerous song, freshwater mermaids of rivers and lakes, and arctic mermaids of the cold north. Every name is original and includes a meaning rooted in water, song, tide, or depth, a readable pronunciation, and a story-ready role.

Naming Customs
Mermaid names favor long open vowels (a, ae, e) and soft sibilants (s, sh, th, l) that evoke water moving over sand and song carrying across a bay. Meanings tend to reference tides, currents, depths, foam, or the call of the open sea rather than land-things. Three-and four-syllable names feel like the deep ocean; shorter names belong to mermaids closer to shore or to the surface. Gendered endings are uncommon in many traditions — mermaids are often a people, not a sex — though names ending in '-a' or '-ia' are sometimes read as feminine-coded sea-spirits, and '-on' or '-us' as masculine-coded storm-callers.
Historical Context
Mermaid myths span the globe. The Greek siren (originally bird-women, later conflated with mermaids) sang sailors to their deaths. The Celtic selkie was a seal-shifter who could shed its skin to walk on land. The Scottish ceasg was a freshwater maid of the lochs. The West African Mami Wata was a powerful water-spirit associated with wealth and healing. The Thai-Cambodian Suvannamaccha was a mermaid princess of the Ramayana. The Chinese Ling Gua was a fish-tailed river-spirit. Across all of these, the naming custom treats the mermaid's name as something heard rather than read — it is sung, or carried on the water, and so its sound matters more than its spelling. In worldbuilding, a mermaid's true name often belongs to the body of water she is tied to, and changes when she migrates.
Cultural Lore
In most worldbuilding contexts, a mermaid's name is sung rather than spoken, as it is believed the spoken word loses its tide. A common taboo involves giving a mermaid a dry name — one with hard land-consonants and no water in it — as these are said to cause the bearer to lose her song. Cultures that revere mermaids associate their names with the blue-green of shallow sea, the silver of fish-scales, the foam-white of breaking waves, and the deep black of the abyssal floor. Siren-variant names carry a sharper, more cutting sound, like the high edge of a wind. Freshwater mermaids take softer, rounder names suggesting rivers and lakes, while arctic mermaids take cold clear names with a crystalline ring. Selkie-derived customs speak of a 'skin-name' — the name a mermaid uses only while in seal or sea-form, hidden from those on land.
