In typography, a serif (/ˈsɛrɪf/) is a small line or stroke regularly attached to the end of a larger stroke in a letter or symbol within a particular font or family of fonts. A typeface or "font family" making use of serifs is called a serif typeface (or serifed typeface), and a typeface that does not include them is sans-serif. Some typography sources refer to sans-serif typefaces as "grotesque" (in German, grotesk) or "Gothic",[1] and serif typefaces as "roman".
