After zeta (Ζ, ζ) in the Greek alphabet, the next letter is eta (Η, η). The Greek alphabet consists of 24 letters, and each has a corresponding uppercase and lowercase form. Eta is the seventh letter of the alphabet and is pronounced like the ‘e’ in ‘met.’
In the sequence of the Greek alphabet, it follows zeta directly, thus continuing the pattern established with preceding letters. Understanding the Greek alphabet is quite important, especially in fields like mathematics and science, where these letters are frequently used as symbols.
