valin

happy

valin adj. "happy" (LT1:272, ). This word, as well as valima and vald-, connect with Tolkien's early concept of Valar meaning "happy ones". Since the term Valar was later reinterpreted as "the Powers", the conceptual validity of these terms for "happy" depends on whether the bliss associated with the Valar and Valinor is regarded as sufficient to give them a secondary justification.
