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.

The Suda or Souda (/ˈsuːdə/; Medieval Greek: Σοῦδα Soûda [ˈsuða]; Latin: Suidae Lexicon) is a large 10th-century Byzantine encyclopedia of the ancient Mediterranean world, formerly attributed to an author called Soudas (Σούδας) or Souidas (Σουίδας). It is an encyclopedic lexicon, written in Greek, with 30,000 entries, many drawing from ancient sources that have since been lost, and often derived from medieval Christian compilers.

In language, an archaism is a word, a sense of a word, or a style of speech or writing that belongs to a historical epoch beyond living memory, but that has survived in a few practical settings or affairs. Lexical archaisms are single archaic words or expressions used regularly in an affair (e.g. religion or law) or freely; literary archaism is the survival of archaic language in a traditional literary text such as a nursery rhyme or the deliberate use of a style characteristic of an earlier age—for example, in his 1960 novel The Sot-Weed Factor, John Barth writes in an 18th-century style. Archaic words or expressions may have distinctive emotional connotations—some can be humorous (forsooth), some highly formal (What say you?), and some solemn (With thee do I plight my troth). The word archaism is from the Ancient Greek: ἀρχαϊκός, archaïkós, 'old-fashioned, antiquated', ultimately ἀρχαῖος, archaîos, 'from the beginning, ancient'.

A distinction between archaic and obsolete words and word senses is widely used by dictionaries. An archaic word or sense is one that still has some current use but whose use has dwindled to a few specialized contexts, outside which it connotes old-fashioned language. In contrast, an obsolete word or sense is one that is no longer used at all. A reader encounters them when reading texts that are centuries old. For example, the works of Shakespeare are old enough that some obsolete words or senses are encountered therein, for which glosses (annotations) are often provided in the margins.

In linguistics, a neologism (/niˈɒlədʒɪzəm/, /ˌniːoʊˈloʊ-/; also known as a coinage) is any newly formed word, term, or phrase that has gained popular or institutional recognition and is becoming accepted into mainstream language.

Neologisms are one facet of lexical innovation, i.e., the linguistic process of new terms and meanings entering a language's lexicon. The most precise studies into language change and word formation, in fact, identify the process of a "neological continuum": a nonce word is any single-use term that may or may not grow in popularity; a protologism is such a term used exclusively within a small group; a prelogism is such a term that is gaining usage but is still not mainstream; and a neologism has become accepted or recognized by social institutions.

In sociolinguistics, a sociolect is a form of language (non-standard dialect, restricted register) or a set of lexical items used by a socioeconomic class, profession, age group, or other social group.

Sociolects involve both passive acquisition of particular communicative practices through association with a local community, as well as active learning and choice among speech or writing forms to demonstrate identification with particular groups. The term sociolect might refer to socially restricted dialects, but it is sometimes also treated as equivalent with the concept of register, or used as a synonym for jargon and slang.

Standard Chinese (simplified Chinese: 现代标准汉语; traditional Chinese: 現代標準漢語; pinyin: Xiàndài biāozhǔn hànyǔ; lit. 'modern standard Han speech') is a modern standard form of Mandarin Chinese that was first codified during the republican era (1912–1949). It is designated as the national lingua franca of China, one of the official languages of the United Nations and of Singapore, and one of the national languages of Taiwan. It is largely based on the Beijing dialect. Standard Chinese is a pluricentric language with local standards in mainland China, Taiwan and Singapore that mainly differ in their lexicon. Hong Kong written Chinese, used for formal written communication in Hong Kong and Macau, is a form of Standard Chinese that is read aloud with the Cantonese reading of characters.

Like other Sinitic languages, Standard Chinese is a tonal language with topic-prominent organization and subject–verb–object (SVO) word order. Compared with southern varieties, the language has fewer vowels, final consonants and tones, but more initial consonants. It is an analytic language, albeit with many compound words.

Lexical semantics (also known as lexicosemantics), as a subfield of linguistic semantics, is the study of word meanings. It includes the study of how words structure their meaning, how they act in grammar and compositionality, and the relationships between the distinct senses and uses of a word.

The units of analysis in lexical semantics are lexical units which include not only words but also sub-words or sub-units such as affixes and even compound words and phrases. Lexical units include the catalogue of words in a language, the lexicon. Lexical semantics looks at how the meaning of the lexical units correlates with the structure of the language or syntax. This is referred to as syntax-semantics interface.
