h₃nómn̥

The neuter n-stem noun *h₃nómn̥ ("name") is one of the most stable lexical items in the Indo-European lexicon. The phonological correspondences are regular across every major branch, and the semantic content — the act of naming, the social function of names — has remained unchanged for at least six millennia. Latin nōmen (genitive nōminis, "name") continues the root with the expected long vowel from *h₃. Derivatives include nominal, nominate, noun (through Old French nom, from Latin nōmen), denominate, nomenclature, ignominious (ignōminia, "without name," i.e., "disgrace"), renown (through Old French renon, from re- + nōmen), and pronoun. The grammatical term "noun" is itself a reflex of this root: a noun is a "name" for a thing. Greek ónoma (ὄνομα, genitive onómatos) shows the regular prothetic o- from *h₃ and the simplification of the initial cluster. Derivatives include onomastics (the study of names), onomatopoeia ("name-making," the creation of words that imitate sounds), anonymous ("without name"), synonym ("with the same name"), and pseudonym ("false name"). The suffix -nym in these compounds is a productive English formation based on the Greek root. Sanskrit nā́man ("name") preserves the nasal stem with full regularity. The verbal derivative nāmáyati ("names, designates") and the formulaic expression nā́ma ("by name") are common in Vedic and classical texts. The concept of nāma-rūpa ("name and form") is a fundamental category in Buddhist philosophy — the naming of things being inseparable from their perceptual form. English name (from Old English nama, Proto-Germanic *namō) shows the regular Germanic development with Grimm's Law: the nasal *n- is preserved (nasals are unaffected by Grimm's Law), and the vowel reflects the o-grade. German Name, Dutch naam, Swedish namn, and Gothic namo continue the same form. Old Irish ainm (with metathesis *nm > *mn > nm > inm) and Welsh enw show the Celtic reflexes with characteristic reshaping. Lithuanian vardas (from a different root, replacing the inherited form) and Old Church Slavonic imę (from *jĭmę, with loss of initial *n-) show more complex developments in Balto-Slavic. Hittite lāman ("name") provides the Anatolian attestation. The initial l- (rather than expected n-) is a long-standing puzzle; one explanation involves a sandhi development in pre-Hittite where the final -n of a preceding word coalesced with the initial *n- of *h₃nómn̥, producing l- by dissimilation. Alternative explanations have been proposed, and the question remains open. The social importance of naming in PIE culture is suggested by the widespread formation of compound personal names across IE traditions: Greek Philo-sophos ("wisdom-lover"), Sanskrit Deva-datta ("god-given"), Germanic Sieg-fried ("victory-peace"), Celtic Vercin-getorix ("over-warrior-king"). The structural parallel across branches suggests an inherited naming convention in PIE society.
