In grammar, a part of speech (also a word class, a lexical class, or a lexical category) is a linguistic category of words (or more precisely lexical items), which is generally defined by the syntactic or morphological behaviour of the lexical item in question. Common linguistic categories include noun and verb, among others. There are open word classes, which constantly acquire new members, and closed word classes, which acquire new members infrequently if at all.
Almost all languages have the lexical categories noun and verb, but beyond these there are significant variations in different languages. For example, Japanese has as many as three classes of adjectives where English has one; Chinese, Korean and Japanese have nominal classifiers whereas European languages do not; many languages do not have a distinction between adjectives and adverbs, adjectives and verbs (see stative verbs) or adjectives and nouns]citation needed[, etc. This variation in the number of categories and their identifying properties entails that analysis be done for each individual language. Nevertheless the labels for each category are assigned on the basis of universal criteria. Object
German verbs may be classified as either weak, with a dental consonant inflection, or strong, showing a vowel gradation (ablaut). Both of these are regular systems. Most verbs of both types are regular, though various subgroups and anomalies do arise. The only completely irregular verb in the language is sein (to be). However, textbooks for foreign learners often class all strong verbs as irregular. There are fewer than 200 strong and irregular verbs, and there is a gradual tendency for strong verbs to become weak]citation needed[.
As German is a Germanic language, the German verb can be understood historically as a development of the Germanic verb.
A split infinitive is an English-language grammatical construction in which a word or phrase, usually an adverb or adverbial phrase, comes between the marker to and the bare infinitive (uninflected) form of a verb.
For example, a split infinitive occurs in the opening sequence of the Star Trek television series: where no man has gone beforeto boldly go. Here, the adverb "boldly" splits the full infinitive "to go". More rarely, the term compound split infinitive is used to describe situations in which the infinitive is split by more than one word: The population is expected to more than double in the next ten years.
