Etymology of the Letter D
Origins of the Alphabet
The origins of the alphabet can be traced back to ancient Mesopotamia, around 1800 BCE, where the Sumerians developed a writing system called cuneiform. This system consisted of wedge-shaped marks made on clay tablets. Over time, the cuneiform script evolved, and various cultures in the Near East, such as the Phoenicians, adopted and modified it to suit their languages.
Phoenician Influence
The Phoenicians were a seafaring civilization that inhabited the coastal areas of modern-day Lebanon, Syria, and Israel. They played a crucial role in spreading writing and alphabet throughout the Mediterranean region. The Phoenicians simplified the cuneiform script, consisting of hundreds of signs, into a more manageable set of about 22 symbols representing consonants.
The Letter Delta in Greek
When the Phoenician alphabet reached the Greeks, they further modified it to suit their language. One of the symbols they adopted was the letter delta (Δ), which represented the “d” sound in their language. The Greek letter delta was shaped like an equilateral triangle, with the top corner pointing upwards, similar to the modern uppercase D.
Development of the Letter D
The letter D as we know it today, both in its uppercase and lowercase forms, gradually evolved from the Greek letter delta. Through the influence of other cultures and languages, such as Latin and Old English, the shape of the letter underwent some changes, but its essential phonetic value remained the same.
