About Troll names
Troll names should sound like stone dragged across stone — guttural consonants, low vowels, and a sense of something old and slow. This generator draws on Norse and Scandinavian folklore, where trolls are creatures of mountain, forest, and bridge, turned to stone by sunlight. Use the subtypes to move between cave trolls, forest trolls, bridge trolls, mountain trolls, and frost trolls of the deep north. Every name is original and includes a meaning rooted in stone, cold, earth, or old patience, a readable pronunciation, and a story-ready role.

Naming Customs
Troll names favor low, heavy vowels (o, u, a) and hard consonants (g, k, r, th, d) that evoke grinding rock and deep cave echoes. Meanings tend to reference stone, frost, earth, or the patient weight of mountains rather than abstract concepts. Names are usually short — one or two syllables — because trolls see no use in sounds that take too long to say. Many trolls carry a 'name-of-nothing' suffix given at birth (a sound that means nothing in any tongue) which they replace with a true name once they have done something worth naming.
Historical Context
Trolls come to us mainly from Norse and Scandinavian folklore, where they are creatures of the wild — larger than humans, often ugly, sometimes giants, and almost always turned to stone if caught by the sun. The Old Norse word 'troll' carried meanings of witch, monster, and heathen being all at once. The Swedish and Norwegian traditions split trolls into mountain trolls (rich, isolated, slow) and forest trolls (slyer, smaller, more dangerous), with bridge trolls a later folktale addition. In all of these traditions, naming a troll is a kind of contract — to name a thing is to have some power over it, which is why trolls in folktales are reluctant to give their names and rage when a human guesses correctly.
Cultural Lore
In most worldbuilding contexts, a troll's name is spoken low and never in daylight, as it is believed that the sun can hear names as well as see bodies. A common taboo involves giving a troll a name with too many bright vowels, as these are said to make the troll 'sun-sick' and prone to wandering into the open. Cultures that live near trolls associate their names with grey stone, dark moss, iron-red earth, and the deep blue of glacial ice. Frost troll names carry a sharper, more cutting sound than their southern cousins, echoing the crack of cold rock. Bridge and road trolls, the ones who deal with travelers, often take names that are slightly easier for humans to say — a kind of trade-name — while keeping their true name hidden.
