S. †thoniel adj. “kindler (in the past)” (Category: to Light, Kindle)
Neo-Sindarin: This perfect participle implies the existence of a verb *than- “to kindle”, but since Tolkien said the participle was archaic, the verb may be as well, and it is probably better to use attested [N.] nartha- for “kindle” in Neo-Sindarin.
