What does styli mean?
Styli is the conventional plural of stylus, a word for a slender writing or drawing instrument and, in modern usage, a pen-like device that interacts with a touchscreen. Classical styli were used to inscribe letters on surfaces such as wax tablets, while contemporary digital styli serve as input devices for tablets, drawing applications, and signature systems. The form “styli” is especially associated with technical, academic, and design contexts, although it is accepted in ordinary English as well. Some speakers and style guides prefer the plural “styluses,” which follows the regular English method of adding -es. Both forms are standard, and the choice depends largely on context and convention rather than a strict distinction in meaning.
