τελεία

Etymology
From, from +.

Noun

 * 1)  A full stop or period ⟨ . ⟩.

Usage notes
Used similarly in Greek punctuation as in French: it marks the ends of sentences, some abbreviations (although it is now standard to write acronyms without them), and groups of three digits in large numbers (where English punctuation uses the comma instead).

Originally referencing the high dot ⟨ ˙ ⟩ in Classical and early Byzantine Greek, τελεία has typically and then universally referenced the low dot ⟨. ⟩ since the advent of printing.
