The most common word for “husband” in Quenya (VT49/45).
Conceptual Development: This word dates all the way back to the Qenya Lexicon of the 1910s where ᴱQ. veru “husband” appeared as a derivative of the early root ᴱ√VEŘE [VEÐE] (QL/101). In the English-Qenya Dictionary of the 1920s the word for “husband” appeared as ᴱQ. vero, but this form was marked as archaic (†) and became in normal speech the longer word ᴱQ. veruner (PE15/74). In Early Noldorin Word-lists and notes on the Valmaric Script from the 1920s the word was still veru (PE13/146; PE14/112), and in the Declension of Nouns from the early 1930s Tolkien gave ᴹQ. veru “husband” as an example of a ū-declension (PE21/15).
In The Etymologies of the 1930s, however, Tolkien gave a different form ᴹQ. venno for “husband” while ᴹQ. veru was a dual form meaning “husband and wife, married pair”, both derived from the root ᴹ√BES “wed” (Ety/BES). The nn in venno is because it was derived from primitive ᴹ✶besnō and sn > zn > nn in Quenya (PE19/49). In a 1969 note, Tolkien restored Q. veru for “husband”, deriving it instead from a root √BER “to mate, be mated, joined in marriage” (VT49/45).
Neo-Quenya: For purposes of Neo-Eldarin, I prefer to retain the 1930s root ᴹ√BES for marriage words in order to preserve Noldorin/Sindarin forms, but I would still use the well-established veru for “husband”, just conceived of as a derivative of the root √BES, coming from ✱besū with intervocalic s > z > r.
veru (1) noun "husband" (VT49:45). An earlier source gives the word for "husband" as venno.
