noun. flash, flash, *lightning

A noun for “a flash” appearing in The Shibboleth of Fëanor as part of a discussion the name Q. Itarillë, S. Idril from the late 1960s, derived from the root √IT (PM/363). It seems to be a bright and direct flash of light, as opposed to ᴹQ. tinde “glint” for a less brilliant and reflected flash of light.

Neo-Quenya: As a flash of light, this word might also be used for “✱lightning” and on this basis used for Neo-Quenya words having to do with electricity.
