Lexicon in the context of "Collocation"

Latin (lingua Latina or Latinum) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally spoken by the Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, including English, having contributed many words to the English lexicon, particularly after the Christianisation of the Anglo-Saxons and the Norman Conquest. Latin roots appear frequently in the technical vocabulary used by fields such as theology, the sciences, medicine, and law.

By the late Roman Republic, Old Latin had evolved into standardised Classical Latin. Vulgar Latin refers to the less prestigious colloquial registers, attested in inscriptions and some literary works such as those of the comic playwrights Plautus and Terence and the author Petronius. While often called a "dead language", Latin did not undergo language death. Between the 6th and 9th centuries, natural language change in the vernacular Latin of different regions evolved into distinct Romance languages. After the fall of the Western Roman Empire, Latin remained the common language of international communication, science, scholarship and academia in Europe into the early 19th century, by which time modern languages had supplanted it in common academic and political usage.

Speech is the use of the human voice as a medium for language. Spoken language combines vowel and consonant sounds to form units of meaning like words, which belong to a language's lexicon. There are many different intentional speech acts, such as informing, declaring, asking, persuading, directing; acts may vary in various aspects like enunciation, intonation, loudness, and tempo to convey meaning. Individuals may also unintentionally communicate aspects of their social position through speech, such as sex, age, place of origin, physiological and mental condition, education, and experiences.

While normally used to facilitate communication with others, people may also use speech without the intent to communicate. Speech may nevertheless express emotions or desires; people talk to themselves sometimes in acts that are a development of what some psychologists (e.g., Lev Vygotsky) have maintained is the use of silent speech in an interior monologue to vivify and organize cognition, sometimes in the momentary adoption of a dual persona as self addressing self as though addressing another person. Solo speech can be used to memorize or to test one's memorization of things, and in prayer or in meditation.

Colloquialism (also called colloquial language, everyday language, or general parlance) is the linguistic style used for casual (informal) communication. It is the most common functional style of speech, the language normally employed in casual conversation and other informal contexts. Colloquialism is characterized by the frequent use of expressive phrases, idioms, anthropocentrism, and a lack of specialized focus, and has a rapidly changing lexicon. It can also be distinguished by its usage of formulations with incomplete logical and syntactic ordering.

A specific instance of such language is termed a colloquialism. The most common term used in dictionaries to label such an expression is colloquial.

A standard language (or standard variety, standard dialect, standardized dialect or simply standard) is any language variety that has undergone substantial codification in its grammar, lexicon, writing system, or other features and that stands out among related varieties in a community as the one with the highest status or prestige. Often, it is the prestige language variety of a whole country.

In linguistics, the process of a variety becoming organized into a standard, for instance by being widely expounded in grammar books or other reference works, and also the process of making people's language usage conform to that standard, is called standardization. Typically, the varieties that undergo standardization are those associated with centres of commerce and government, used frequently by educated people and in news broadcasting, and taught widely in schools and to non-native learners of the language. Within a language community, standardization usually begins with a particular variety being selected (often towards a goal of further linguistic uniformity), accepted by influential people, socially and culturally spread, established in opposition to competitor varieties, maintained, increasingly used in diverse contexts, and assigned a high social status as a result of the variety being linked to the most successful people. As a sociological effect of these processes, most users of a standard dialect—and many users of other dialects of the same language—come to believe that the standard is inherently superior to, or consider it the linguistic baseline against which to judge, the other dialects. However, such beliefs are firmly rooted in social perceptions rather than any objective evaluation. Any varieties that do not carry high social status in a community (and thus may be defined in opposition to standard dialects) are called nonstandard or vernacular dialects.

Although English is classed as a Germanic language, it has been strongly influenced by Latin—primarily in its lexicon. Though the grammar and core vocabulary of English are inherited from Proto-Germanic, a great deal of English vocabulary comes from Romance and Latinate sources. The vast majority of these borrowings come either direct from Latin or indirectly from French; there are also a few borrowings from Italian, Portuguese, and Spanish. Other borrowings have come from Gothic or Frankish via French or Greek via Latin.

Lexicography is the study of lexicons and the art of compiling dictionaries. It is divided into two separate academic disciplines:

• Practical lexicography is the compiling, writing, and editing of dictionaries.
• Theoretical lexicography is the scholarly study of semantic, orthographic, syntagmatic, and paradigmatic features of lexemes of the lexicon (vocabulary) of a language, developing theories of dictionary components and structures linking the data in dictionaries, the needs for information by users in specific types of situations, and how users may best access the data incorporated in printed and electronic dictionaries. This is sometimes referred to as "metalexicography" as it is concerned with the finished dictionary itself.

There is some disagreement on the definition of lexicology, as distinct from lexicography. Some use "lexicology" as a synonym for theoretical lexicography; others use it to mean a branch of linguistics pertaining to the inventory of words in a particular language.

In sociolinguistics, a variety, also known as a lect or an isolect, is a specific form of a language or language cluster. This may include languages, dialects, registers, styles, or other forms of language, as well as a standard variety. The use of the word variety to refer to the different forms avoids the use of the term language, which many people associate only with the standard language, and the term dialect, which is often associated with non-standard language forms thought of as less prestigious or "proper" than the standard. Linguists speak of both standard and non-standard (vernacular) varieties as equally complex, valid, and full-fledged forms of language. Lect avoids the problem in ambiguous cases of deciding whether two varieties are distinct languages or dialects of a single language.

Variation at the level of the lexicon, such as slang and argot, is often considered in relation to particular styles or levels of formality (also called registers), but such uses are sometimes discussed as varieties as well.
