tittle, noun = a small mark in printing or writing, especially a diacritic
Origin: from Latin titulus – label
I came across this word while researching the origin of the dot on the letters i and j, which is known as a tittle. This diacritic was apparently first used to distinguish the letter i from other letters in Latin manuscripts during the 11th century. Originally the tittle was bigger, but was reduced in size gradually until it reached its current dimensions.
