The uppercase letter Η is used as a symbol in textual criticism for the Alexandrian text-type (from Hesychius, its once-supposed editor). In chemistry , the letter H as symbol of enthalpy sometimes is said to be a Greek eta, but since enthalpy comes from ἐνθάλπος, which begins in a smooth breathing and epsilon, it is more likely a ...
Iota subscripts in the word ᾠδῇ, ("ode", dative) The iota subscript is a diacritic mark in the Greek alphabet shaped like a small vertical stroke or miniature iota ι placed below the letter. It can occur with the vowel letters eta η , omega ω , and alpha α .

In these contexts, the capital letters and the small letters represent distinct and unrelated entities.
The symbol Z is used to represent it and it is expressed in units of ohms. The symbol η ( eta ) may be used instead of Z for wave impedance to avoid confusion with electrical impedance . Definition
