Which Greek letter is represented by 'T'?

The letter 'T' in the Greek alphabet is represented by "Tau." Each letter in the Greek alphabet has a corresponding name and sound, and Tau is specifically the letter that corresponds to the English 'T' sound.

In contrast, letters like Pi, Sigma, and Alpha correspond to different phonetic sounds and thus are not related to the letter 'T.' Pi represents a 'P' sound, Sigma represents an 'S' sound, and Alpha represents an 'A' sound. Understanding the Greek alphabet and the respective letters is essential for grasping their significance in various contexts, including mathematics, science, and fraternity or sorority life where these letters are often used for naming.
