High Quality Content by WIKIPEDIA articles! The following is a list of creatures from the NBC television series Grimm, called Wesen. Wesen is German for `creature` or `essence.` Although the names of many of the Wesen listed below are compounds of German words, they are not truly German names in the sense that these creatures do not exist by these names in the Grimms` tales, nor are they referred to as such in spoken or written German. Further, the words are not always pronounced using German diction and plural forms. For example, in the series, `Wesen` is pronounced VESS-en with the first vowel short and the second even further reduced, while the actual German word is pronounced VAY-zen.
