Can you give me an example of a sentence that uses an infinitive in it?

In morphology and lexicography, a lemma (plural lemmas or lemmata) is the canonical form, dictionary form, or citation form of a set of words (headword)]citation needed[. In English, for example, run, runs, ran and running are forms of the same lexeme, with run as the lemma. Lexeme, in this context, refers to the set of all the forms that have the same meaning, and lemma refers to the particular form that is chosen by convention to represent the lexeme. In lexicography, this unit is usually also the citation form or headword by which it is indexed. Lemmas have special significance in highly inflected languages such as Turkish and Czech. The process of determining the lemma for a given word is called lemmatisation.

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.

In grammar, tense is a category that locates a situation in time, to indicate when the situation takes place. Tense is the grammaticalisation of time reference, often using three basic categories of "before now", i.e. the past; "now", i.e. the present; and "after now", i.e. the future. The "unmarked" reference for tense is the temporal distance from the time of utterance, the "here-and-now", this being absolute-tense. Relative-tense indicates temporal distance from a point of time established in the discourse that is not the present, i.e. reference to a point in the past or future, such as the future-in-future, or the future of the future (at some time in the future after the reference point, which is in the future) and future-in-past or future of the past (at some time after a point in the past, with the reference point being a point in the past).

Not all languages grammaticalise tense, and those that do differ in their grammaticalisation thereof. Languages without tense are called tenseless languages and include Burmese, Dyirbal and Chinese. Not all grammaticalise the three-way system of past–present–future. For example, some two-tense languages such as English and Japanese express past and non-past, this latter covering both present and future in one verb form, whereas others such as Greenlandic and Quechua have future and non-future. Four-tense languages make finer distinctions either in the past (e.g. remote vs. recent past), or the future (e.g. near vs. remote future). The six-tense language Kalaw Lagaw Ya of Australia has the remote past, the recent past, the today past, the present, the today/near future and the remote future. The differences between such finer distinctions are the distance on the timeline between the temporal reference points from the present.

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.

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.

In journalism, a human interest story is a feature story that discusses a person or people in an emotional way. It presents people and their problems, concerns, or achievements in a way that brings about interest, sympathy or motivation in the reader or viewer.

Human interest stories may be "the story behind the story" about an event, organization, or otherwise faceless historical happening, such as about the life of an individual soldier during wartime, an interview with a survivor of a natural disaster, a random act of kindness or profile of someone known for a career achievement.
