What a name tells you, and who gets to give one

The system most administrative forms assume — one given name, one inherited family name, both fixed for life — is neither universal nor old. It became standard in many places only when states needed to track individuals for taxation, conscription and property records.

What existed before, and what still exists alongside it, is considerably more varied.

Patronymics

The most widespread alternative. A person's second name identifies their father: son of, daughter of.

Under a true patronymic system, the name changes every generation, so siblings share it and a father and child do not. Iceland maintains this, which is why Icelandic phone directories are ordered by given name — the second name is not a family identifier.

Many European surnames are frozen patronymics: names meaning "son of" in various languages became hereditary at the point where records demanded fixity. The same underlying pattern produced surnames across Wales, Scandinavia, Russia, the Iberian peninsula and the Slavic world, with different suffixes.

Russian practice retains a live patronymic alongside a hereditary surname, and the patronymic is used in polite address, which is a distinction that translates badly.

Where the name comes from a place, a job or a description

The other major sources of European surnames.

Toponymic — from a place, either a settlement or a landscape feature. Common where people moved and were identified by where they came from.

Occupational — from a trade. These are so common across languages that the same handful of trades appear repeatedly: smith, miller, baker, weaver, carpenter.

Descriptive — from a physical characteristic, a temperament or a nickname, which is how a surprising number of surnames that now seem neutral originated as something less flattering.

Clan and lineage systems

In many societies, the crucial name identifies a descent group rather than a nuclear family.

Scottish clan names, Irish and Welsh lineage systems, and clan names across many African, Central Asian and Pacific societies all function this way. Membership carries obligations — mutual support, marriage prohibitions, land rights — and the name is a statement about those obligations rather than about parentage.

Exogamy rules frequently attach to clan names, meaning that the name determines who a person may not marry, which is one of the more consequential things a name can do.

Names that change across a life

The assumption that a name is fixed is far from universal.

Many traditions have a birth name, a childhood name, an adult name given at initiation, and sometimes further names on marriage, on achieving something, or on becoming a parent or grandparent.

Teknonymy — being addressed as the parent of a named child — is documented in a range of societies, where after a first child is born the parents are referred to by that relationship rather than by their own names.

Some traditions avoid naming the dead, requiring living people who share the name to take a new one. Some avoid speaking the names of certain relatives entirely, requiring circumlocution.

Order and address

Family name first is standard across much of East Asia and in Hungary, among others, and it is a straightforward difference that Western administrative systems handle badly — producing decades of records in which names have been reversed by well-meaning clerks.

Spanish and Portuguese practice uses two family names, from both parents, with conventions about order that differ between the two traditions. Reducing these to a single surname on a form loses information about which is which.

Arabic naming can incorporate a given name, a patronymic chain, a family or tribal name, and a name derived from a place or an attribute, with which element is used in address depending on context.

Names and the state

The push toward fixed hereditary surnames was overwhelmingly administrative, and it was frequently imposed.

Various states required populations to adopt fixed surnames at particular moments, sometimes with the names assigned by officials. Colonial administrations imposed naming conventions on populations with entirely different systems, and residential school systems in several countries renamed children as a matter of policy.

The consequence is that a great many people's surnames record an act of administration rather than a family history, and in some communities the recovery of pre-imposition naming practices is an active project.

What this means practically

Any form with fields for "first name" and "last name" encodes assumptions that fail for a large share of the world's population, and the failures are not trivial — mismatched names cause problems with travel documents, medical records and legal identity.

The straightforward correction, used by some systems, is a single full-name field plus a separate field for how the person wishes to be addressed. It handles every system, including the ones nobody thought of, and it removes the small daily insult of having your name declared malformed by a database.
