Bullet vs Middle Dot

The bullet (•, U+2022) is a large, filled circle used to introduce items in an unordered list, while the middle dot (·, U+00B7) — also called the interpunct — is a much smaller centered dot historically used as a word separator in ancient Latin inscriptions and in modern use for separating list items inline or in linguistic notation. Visually, the bullet is noticeably larger and bolder, sitting at mid-height, making it easy to spot at a glance in lists; the middle dot is petite and subtle. The middle dot (U+00B7) is also used in chemistry to denote hydrates (CuSO₄·5H₂O), in mathematics as a multiplication operator in some traditions, and in Catalan orthography to mark a geminated L (l·l). The hyphenation point (U+2027) looks similar to the middle dot but is specifically a punctuation mark suggesting a word-break opportunity, used in dictionaries and linguistic texts. In HTML, the bullet can be produced with • and the middle dot with · or ·.
