A book hand was any of several stylized handwriting scripts used during ancient and medieval times. It was intended for legibility and often used in transcribing official documents (prior to the development of printing and similar technologies).
In palaeography and calligraphy, the term hand is still used to refer to a named style of writing, such as the chancery hand.
Fraktur (German: [fʁakˈtuːɐ̯] ) is a calligraphic hand of the Latin alphabet and any of several blackletter typefaces derived from this hand. It is designed such that the beginnings and ends of the individual strokes that make up each letter will be clearly visible, and often emphasized; in this way it is often contrasted with the curves of the Antiqua (common) typefaces where the letters are designed to flow and strokes connect together in a continuous fashion. The word "Fraktur" derives from Latin frāctūra ("a break"), built from frāctus, passive participle of frangere ("to break"), which is also the root for the English word "fracture". In non-professional contexts, the term "Fraktur" is sometimes misused to refer to all blackletter typefaces – while Fraktur typefaces do fall under that category, not all blackletter typefaces exhibit the Fraktur characteristics described above.
