Standard English in the context of "Atomic physics"

African-American Vernacular English (AAVE), sometimes formerly known as Ebonics, is the variety of English natively spoken by most working and middle-class African Americans, particularly in urban communities. This variety is also spoken amongst some Black Canadians. Having its own unique grammatical, vocabulary, and accent features, AAVE is employed by middle-class Black Americans as the more informal and casual end of a sociolinguistic continuum. However, in formal speaking contexts, speakers tend to switch to more standard English grammar and vocabulary, usually while retaining elements of the vernacular (non-standard) accent. AAVE is widespread throughout the United States, but it is not the native dialect of all African Americans, nor are all of its speakers African American.

Like most varieties of African-American English, African-American Vernacular English shares a large portion of its grammar and phonology with the regional dialects of the Southern United States, and especially older Southern American English, due to the historical enslavement of African Americans primarily in that region.

In linguistics, agreement or concord (abbreviated agr) occurs when a word changes form depending on the other words to which it relates. It is an instance of inflection, and usually involves making the value of some grammatical category (such as gender or person) "agree" between varied words or parts of the sentence.

For example, in Standard English, one may say I am or he is, but not "I is" or "he am". This is because English grammar requires that the verb and its subject agree in person. The pronouns I and he are first and third person respectively, as are the verb forms am and is. The verb form must be selected so that it has the same person as the subject in contrast to notional agreement, which is based on meaning.

An airman is a member of an air force or air arm of a nation's armed forces. In certain armed air forces, it may pertain to a defined and established enlisted rank. An airman might occasionally referred to as a soldier in different definitions. In 1873 it referred only to males who flew balloons during the beginning of modern aviation history. For a official military position, it conforms to the conventions of Standard English, and in turn, both male, and female participants.

A subtype, referred to as an aviator, is often designated for civilian use. Since the United States Air Force was established in 1947, all of the various ranks of "airman" have always included women, and in this context, the word "man" means "human being". Notably the term airman is commonly known as "dirtbag airman" in the United States after a United States Air Force aviator used urine to stop a fire while fighting Nazi planes in Nazi Germany and later received the Medal of Honor. It is common for ones Navy to refer to a airman as a aviator.

Ulster Scots or Ulster-Scots (Ulstèr-Scotch), also known as Ulster Scotch and Ullans, is the dialect of Scots spoken in parts of Ulster, being almost exclusively spoken in parts of Northern Ireland and County Donegal. It is normally considered a dialect or group of dialects of Scots, although groups such as the Ulster-Scots Language Society and Ulster-Scots Academy consider it a language in its own right, and the Ulster-Scots Agency and former Department of Culture, Arts and Leisure have used the term Ulster-Scots language.

Some definitions of Ulster Scots may also include Standard English spoken with an Ulster Scots accent. This is a situation like that of Lowland Scots and Scottish Standard English with words pronounced using the Ulster Scots phonemes closest to those of Standard English.Ulster Scots has been influenced by Hiberno-English, particularly Ulster English, and by Ulster Irish. As a result of the competing influences of English and Scots, varieties of Ulster Scots can be described as "more English" or "more Scots".

African-American English (AAE) is the umbrella term for English dialects spoken predominantly by Black people in the United States and, less often, in Canada; most commonly, it refers to a dialect continuum ranging from African-American Vernacular English to more standard American English. Like all widely spoken language varieties, African-American English shows variation stylistically, generationally, geographically (that is, features specific to singular cities or regions only), in rural versus urban characteristics, in vernacular versus standard registers, etc. There has been a significant body of African-American literature and oral tradition for centuries.

In linguistic typology, a subject–object–verb (SOV) language is one in which the subject, object, and verb of a sentence always or usually appear in that order. If English were SOV, "Sam apples ate" would be an ordinary sentence, as opposed to the actual Standard English "Sam ate apples" which is subject–verb–object (SVO).

The term is often loosely used for ergative languages like Adyghe and Basque that in fact have agents instead of subjects.
