Etymology
GermanicEnglish
Derek comes from the old Germanic name Theodoric, which is made up of two parts: 'þeud' meaning 'people' and 'rīk' meaning 'ruler' or 'king.' So the name originally meant 'ruler of the people.' It came into English through Dutch and Low German forms in the Middle Ages and became a common first name in Britain and other English-speaking countries.
