Guarani Names

Structure & order

Personal names follow the Spanish four-part model: [GIVEN1] [GIVEN2] [PATERNAL_SURNAME] [MATERNAL_SURNAME]. The paternal surname precedes the maternal surname. The two-surname inheritance is long-standing custom and was explicitly recognized for official documents in Paraguay's 1992 Constitution. See Name Ordering and Surname Formation; the underlying Hispanic system is shared with Spanish Names.

Given names

Most given names are Spanish/Catholic (José, María, Juan; girls very often named María, frequently in composites like María de los Ángeles, with only the final element used day to day). Alongside these, Guaraní given names carry transparent meanings drawn from nature and spirituality, e.g. Ára "sky/heavens" (diminutive Arami), Amambái/Amambay "fern", Amaru "rain", Amapytu "spirit of the rain". Male names commonly end in -o, female in -a under Spanish influence. The use of meaningful Guaraní given names is part of a broader cultural-revival trend (uncertain in scale; see pitfalls).

Family names & patronymics

Both surnames are inherited (paternal then maternal); women generally keep their maiden surnames for life, even after marriage. Surnames may be linked by particles y "and", de "of", or e "and" (before an i-sound). Many surnames are Guaraní or hispanicized Guaraní: e.g. Yahari (reportedly the most common Guaraní surname, ~2,000+ bearers, glossed "we don't believe what we are told"), and forms hispanicized at baptism such as Arandá → Aranda, Berá → Vera. Fixed surnames were imposed on Guaraní people during 16th-century colonization, replacing fluid, descriptive Indigenous names.

How to address someone

Spanish-language conventions apply: Señor / Señora / Señorita + surname formally; Don / Doña + given name as a respectful familiar address. Guaraní is widely used in informal and intimate registers. See Salutations and Address.

Pitfalls for software

• Co-officiality is linguistic, not onomastic: the name system is overwhelmingly Spanish even where speech is Guaraní. Parsers should expect Hispanic two-surname structure regardless of language tag.
• Guaraní-origin tokens often surface as surnames (and as given names used as surnames), so a Guaraní-looking token is not reliably a given name.
• Hispanicization variants (Berá/Vera, Arandá/Aranda) mean the same family can appear under spelling variants; nasal/accent marks may be stripped in records.
• The scope of contemporary Guaraní given-name revival is plausible but thinly sourced here; treat as a trend, not a quantified phenomenon.
