entya

central, middle

entya, enetya adj. "central, middle" (VT41:16; these forms, as well as the noun entë "centre", come from a late, somewhat confused source; the adjective #endëa and the noun endë from earlier material may fit the general system better, and #endëa is even found in the LotR itself as part of the word atendëa, q.v.)
