From Wikipedia:

Fraktur is a calligraphic hand of the Latin alphabet and any
of several blackletter typefaces derived from this
hand. The blackletter lines are broken up; that is, their forms contain
many angles when compared to the smooth curves of the Antiqua (common)
typefaces modeled after antique Roman square capitals and Carolingian
minuscule. From this, Fraktur is sometimes contrasted with the “Latin
alphabet” in northern European texts, which is sometimes called the
“German alphabet,” simply being a typeface of the Latin alphabet.
