A name can be excellent in one system and unregisterable in another.
Compare criteria; do not flatten them into a single global score.
Regions
- Iceland — Grammar + list
A good given name inflects correctly and usually appears on the accepted list.
- Germany — Gender and order rules
Namensrecht treats a good name as one that will not harm the child and fits sex-marking norms (evolving).
- Japan — Approved kanji
Goodness includes being writable on the koseki with jinmeiyō or jōyō characters.
- Korea — Hanja optional, 돌림자 social
KOSTAT counts popularity; families may still design generation syllables as kin craft.
- Spanish-speaking states — Two-surname integrity
A good official name often preserves both parental surnames.
- Anglophone web — Handle availability
A good name increasingly means a free username — a new, brittle test.
Laws
- Naming law (general) Many states — Restrictions on numerals, titles and offensive strings are quality rules written as law.
- German Namensrecht Germany — The civil status office can refuse a name that endangers the child’s welfare.
- Icelandic personal names act Iceland — Committee plus grammar — high legal friction as a definition of good.
- Japanese Family Register Act Japan — Character lists make “good” partially a font-and-code-point problem.
Quality is local. The atlas’s job is to name the local test.
