Note
A regular English plural, made with plain -s, and it serves every noun spelled eta. That includes the Greek letter, which is seventh in the modern alphabet and eighth in the ancient one. It also covers the neutral, spinless meson of particle physics and a variant spelling of ita, a kind of palm. Context decides which is meant: a physicist's etas are particles, a manuscript's are letters.
