Telli is of Turkish origin, meaning 'shiny' or 'bright'. It's composed of two elements: 'tel', meaning 'shine', and the diminutive suffix '-li'. This name was popularized by the poet Telli Hagopian, who wrote under the pseudonym Telli. In Turkey, it's often used for girls but can also be given to boys.
"Telli is quite rare; only 11 babies were named Telli between 1974 and 1975."
