A word for “brother” coined by Tolkien in notes on Eldarin Hands, Fingers and Numerals from the late 1960s, based on the root √KHAN of the same meaning (VT47/14). It had a diminutive/affectionate variant hanno used as a play name for the middle finger in several places in these notes (VT47/12; VT48/6).
Conceptual Development: The Etymologies of the 1930s had ᴹQ. toron “brother” from the root ᴹ√TOR (Ety/TOR), and the Qenya Lexicon of the 1910s had ᴱQ. herendo “brother” from the early root ᴱ√HESE (QL/40). See those entries for discussion.
háno noun "brother", colloquially also hanno (VT47:12, 14). It is unclear whether Tolkien, by introducing this form, abandoned the older (TLT) word toron (q.v.)
