nav n (singular definite navet, plural indefinite nav)
- nave (a hub of a wheel)
From Proto-Iranian (compare Persian نام (nâm), Pashto نوم (nūm), Avestan 𐬥𐬁𐬨𐬀𐬥 (nāman-)) from Proto-Indo-Iranian *HnaHman- (compare Sanskrit नामन् (nā́man), Hindi नाम (nām)), from Proto-Indo-European *h₁nḗh₃mn̥ (“name”) (compare Greek όνομα (ónoma), Italian nome, Tocharian A ñom, Armenian անուն (anun), Danish navn, and English name).
nav gender unspecified
Reduced form of navaid from nevaid (both still attested in Latvian dialects), originally the negative form of vaid (“to be located, to be”). (G. F. Stenders, in his 1774 grammar, mentions under nevaid the reduced forms neva, nava and even nav' with an apostrophe.) This form replaced an earlier neir, neira (from ir, ira); compare Lithuanian nėrà from neyrà. Forms of vaid are occasionally attested in folk tales and songs; A. Bīlenšteins once heard its infinitive form vaist. It was probably an old perfect form, from Proto-Indo-European *weyd- (“to see, to know”) (“to see (around, where one is)” > “to find oneself, to be located, to be”); cf. Lithuanian vaidalas (“apparition, ghost”).
