Meister

Meister means 'master' in German (as in master craftsman, or as an honorific title such as Meister Eckhart). The word is akin to master and maestro. In sports, "Meister" is used for the current national, European or world champion (e.g. "Deutscher Meister", "Europameister", "Weltmeister"). 
During the Second World War, "Meister" was the highest enlisted rank of the German "Ordnungspolizei". Many modern-day German police forces also use the title of "Meister".
"Meister" has been borrowed into English slang, where it is used in compound nouns. A person referred to as “Meister” is one who has extensive theoretical knowledge and practical skills in his profession, business, or some other kind of work or activity. For example, a “puzzle-meister” would be someone highly skilled at solving puzzles. These neologisms sometimes have a sarcastic intent (for example, “stubble-meister” for someone with a short, neat beard, or “crier-meister” for someone who often cries).
Professional degree.
In Germany and Austria, the word "Meister" also assigns a title and public degree in the field of vocational education. The German "Meister" title qualifies the holder to study at a University or "Fachhochschule", whether the "Meister" holds the regular entry qualification ("Abitur" or "Fachhochschulreife") or not.[1] In 2012, the commissions of the states and the federal government, as well as the associated partners, concluded that the "Meisterbrief" is equivalent to a bachelor's degree ("Deutscher Qualifikationsrahmen für lebenslanges Lernen" and "European qualification framework EQF, Level 6, Niveau 6). In the year 2020 plans were finalised to rename the meister title to "professional bachelor"
The Master craftsman is the highest professional qualification in crafts and is a state-approved grade. The education includes theoretical and practical training in the craft and also business and legal training, and includes the qualification to be allowed to train apprentices as well. The status of Master craftsman is regulated in the German "Gesetz zur Ordnung des Handwerks, HwO" (Crafts and Trades Regulation Code).
To become a master craftsman usually requires vocational training in the specific crafts in which the examination should be taken (a successfully completed apprenticeship and examination, called "Gesellenprüfung"). In addition to attaining the journeyman ("Geselle") degree, until 2004 the Crafts and Trades Regulation Code did furthermore require practical experience of 3 years as a journeyman. In the German field of "Meister" education, specialised training courses for the "Meisterprüfung" ("Meister examination") can be followed. The duration of the courses can take 1 to 2 years. The examination includes theoretical, practical and oral parts and takes 5 to 7 days (depending on the craft). In some crafts, the creation of a masterpiece is also part of the examination.
Etymology.
"Meister" is derived from the Greek word "μήστωρ" (adviser, counselor, adept, scientist), the Latin word "magister" (teacher), the German "meister" from Old High German "meistar", and the Yiddish "mayster".
