“The dot over the letters i and j is called a tittle”

We often encounter tiny details in our written language that we use daily without ever giving them a second thought, let alone knowing their proper names. One such unassuming element is the small mark that graces the top of the lowercase 'i' and 'j'. While many might simply refer to it as "the dot," it actually possesses a specific and rather charming name, and the common idea that it lacks one is a misconception.

Indeed, the diminutive distinguishing mark perched above the lowercase letters i and j is officially known as a tittle. This fascinating term has roots in the Latin word titulus, which translates to "small mark" or "superscription." Historically, these seemingly minor flourishes were crucial in distinguishing letters and aiding readability, especially in early manuscripts where clarity could be challenging. It stands as one of the smallest, yet most universally recognized, components within our typographic landscape.

The reason this piece of linguistic trivia might feel like a myth to many isn't due to widespread misinformation, but rather a simple lack of exposure. Typographic terminology, while rich and precise, isn't typically part of everyday conversation or elementary education. Most people learn to read and write without ever needing to label every minute component of a letter, leading to a general unawareness of such specific terms. It's a classic example of how specialist vocabulary remains largely unknown outside its particular field, making a well-established fact seem like a hidden secret.
