The term ᴱQ. hesta appeared in the Qenya Lexicon of the 1910s with the gloss “the nearest consanguinity” (QL/40), that is the closest relative sharing a common ancestor, usually a sibling but possibly cousins if one has no siblings. The form hesta is followed by (-le) in parenthesis, which usually indicates a stem form but in this case probably indicates a variant form hestale. This word is derived from the early root ᴱ√HESE.
