A verb appearing as ᴱQ. hyal- “ring, resound” in Early Qenya Word-lists of the 1920s (PE16/144), possibly related to the 1930s root ᴹ√SYAL having to do with sea shells if the underlying meaning was resonant sounds (Ety/SYAL); see that root’s entry for discussion.

Neo-Quenya: Given the (possible) survival of its root, I would retain ᴺQ. hyal- “to ring, resound” for purposes of Neo-Quenya.
