Below is a list of German expressions used in English. Some are relatively common (such as hamburger or gestalt), but most are comparatively rare. In many cases, the German borrowing in English has assumed a substantially different meaning than its German forebear.
Although the English language was originally based on an Anglo-Saxon variant of the German language similar to Dutch before the Norman Conquest of England by Norman-speaking peoples in 1066 (see Old English), many modern German words have been borrowed into modern English in more recent years. Typically English spellings of German loanwords suppress any umlauts (the accent over Ä, Ö, Ü, ä, ö and ü) of the original artifact.
German words have been incorporated into English usage for various reasons. Common cultural items, especially foods, have spread to English-speaking nations and are often identified by their German names. The history of excellence among German-speaking nations in science, scholarship, and classical music has led to many German words being adopted by academics for use in English contexts. Discussion of German history and culture requires use of German words. Lastly, some German words are used simply to a fictional passage by implying that the thing being expressed is German, as in Frau or Reich, although sometimes the use of German terms has no German implication, as in doppelganger or angst.
English and German are descended from the same common ancestor, called Proto-Germanic. Because of this, a number of English words are identical to their German counterparts either in spelling (Hand, Finger) or in pronunciation (Fish = Fisch). These words are excluded from this list.
Words in this category will be recognized by most English speakers and are commonly used in English. A few, such as delicatessen and hinterland, are often used without awareness that they are originally German. It should be noted that some words in this list (hamburger, kindergarten) are more common than others (ersatz, wanderlust).
Foosball (German spelling: Fußball, which refers to the game called soccer in the United States) - in US English, foosball refers exclusively to the tabletop soccer games found in bars and pubs, which are called Tischfußball, Wuzzler or Kicker in German, and simply table football in the UK.
German terms commonly used in academic contexts in English
German terms frequently appear in several academic disciplines in English, notably in history, psychology, philosophy, music and the physical sciences. Non-specialists in a given field may or may not be familiar with a given German term.
Führer (umlaut is usually dropped in English) — always used in (American) English to denote Hitler or to connote a Fascistic leader — never used, as is possible in German, simply and unironically to denote a (non-Fascist) leader, i.e. Bergführer just means Mountain Guide
Herr — evokes German context; but used with military titles ("Herr Oberst"), immediately connotes Nazi era to (American) English listeners.
Lederhosen (Singular Lederhose in German denotes one pair of leathery trousers. The original Bavarian word is Lederhosn, which is both singular and plural.)
Meister — used as a suffix to mean expert, or master
Reich — to (American) English speakers, "Reich" does not denote its literal meaning, "empire", but strongly connotes Naziism and is often used to suggest Fascism or authoritarianism, e.g., "Herr Reichsminister" used as a title for a disliked politician. German "reich" as an adjective means rich, as a noun it means empire.
Jawohl has no literal translation in English, but is often equated to "yes sir".
Schnell! — Fast!
Kommandant — officer or person in command, especially of a military camp or U-Boat. (Applies regardless of military rank, in distinction to the English "commander".)
