T: The Twentieth Letter of the Alphabet

Etymology

The letter T comes from the Phoenician letter taw, which symbolized a “mark” or “cross.” It was adopted by the Greeks as tau and later by the Romans into the Latin alphabet. T became the twentieth letter of the English alphabet and typically represents the voiceless alveolar plosive sound (/t/), as in “top.”
