Frühneuhochdeutsch
Fechtbuch (plural Fechtbücher) is Early New High German for "combat manual", one of the manuscripts or printed books of the late Middle Ages and the Renaissance containing descriptions of a martial art. Usually, the term is taken to include 15th- and 16th-century German manuals, but the nature of the subject matter does not allow a clear separation of these from treatises from other parts of Europe on one hand (particularly from the Italian and French schools), and from manuals of later centuries on the other hand.
