Pronounced (nâz'-tair) it is an intimate Householding term of address to a fellow member of a Householding. 

Examples: "Naztehr Hugh" is Hugh Valleroy after his nager makes it obvious to Zeor Simes that he has pledged to Klyd (even when Hugh, himself, does not know it.)  (Source:   House of Zeor.)

(Source:  Index card file.  House of Zeor)  Addressed only to members of a Householding, although Klyd calls Hugh this when he wants him to obey.  "The most intimate Householding term of membership" -- Feleho's use of this term thrills Hugh, motivates him tremendously.  Klyd addresses Enam as "Naztehr"  --- a renSime!

(Source:  Index card file.  "Naztehr" --- Attributed to a conversation by Jean Lorrah)  The Simelan for "wer-Gen."  Used by Gens originally in same spirit as they call themselves "Gens." (Simelan word for "those Pen animals.")
