The adjective (Latin: ad iectivum, from Ancient Greek epí theton, the added or descriptive word, also called a "Wiewort" in elementary school) is a part of speech in linguistics that describes the quality or a relation of a (concrete) thing, an (abstract) concept, a process, or a state. According to the traditional word paradigm, the parts of speech adjective and adverb (circumstantial word) are distinguished. Adverbs are associated with the verb (Latin: ad verbum), but not with the auxiliary verb. They are not inflected, but can occasionally be compared. Occasionally, adjectives (in the traditional sense) and adverbs are grouped together as adjectives in a broader sense.
