Etymology
The letter eta originated from the Phoenician letter heth, which represented a sound similar to 'h'. The Greeks adapted this letter around the 8th century BCE and redefined its phonetic value. Initially, eta represented a long 'e' sound, but over time, the pronunciation shifted in various dialects. The uppercase form of eta is 'Η', and the lowercase is 'η'. Throughout history, eta has been employed in various academic disciplines, adapting its use to fit modern linguistic and scientific needs. Today, it is often noted in contexts that require precision, such as mathematics and physics, illustrating how a letter can evolve and find relevance in diverse fields.
