Just exactly like what is sounds, a sans-serif typeface is a typeface without serifs. They can be found in history as early as the 5th century, although the classical revival of the Italian Renaissance return to old style serifed typefaces made them virtually obsolete until the 20th century. Their was much development of sans-serif typefaces in Germany as a revolt against the ornate lettering of the popular Blackletter styles which led to sans-serif typefaces based on the purity of geometric forms. Much like serifed typefaces, there are many different classifications for sans-serif typefaces, including Gothic, Grotesque, Doric, Linear, Swiss and Geometric. Some of the broader classifications are listed below.
