Haran

haran is a Quenya word. In The Etymologies, its meaning is given as "chieftain", related to Sindarin Aran, 'king". In later appearances, it seems to have been replaced by aran, like in Aranwë.

In neo-eldarin studies, haran is believed to be the Quenya word for the number one-hundred, see the quote below. Since the Númenóreans were the only to use decimal system, it is possibly a dialect word.

"100 may be *haran - in LotR:1142, we find a reference to "the last [year] of a century (haranyë)". It is not clear from the wording if a haranyë is a century or just the last year of it, but the form of the word itself suggests the latter: If *haran is 100, *haranya would be "hundredth" and haranyë a nominalized form *"hundredth one"."
