The order of an element of a group (also called period length or period) is the order of the subgroup generated by the element. If the group operation is denoted as a multiplication , the order of an element a of a group, is thus the smallest positive integer m such that a m = e , where e denotes the identity element of the group, and a m ...
In group theory, a word is any written product of group elements and their inverses. For example, if x, y and z are elements of a group G, then xy, z −1 xzz and y −1 zxx −1 yz −1 are words in the set {x, y, z}. Two different words may evaluate to the same value in G, [1] or even in every group. [2]
Categorization is a type of cognition involving conceptual differentiation between characteristics of conscious experience, such as objects, events, or ideas.It involves the abstraction and differentiation of aspects of experience by sorting and distinguishing between groupings, through classification or typification [1] [2] on the basis of traits, features, similarities or other criteria that ...

Sometimes the date of the image is important: there is a difference between "King Arthur" and "King Arthur in a 19th-century watercolor". Photographs and other graphics need not have captions if they are "self-captioning" images (such as reproductions of album or book covers) or when they are unambiguous depictions of the subject of the article.
In linguistics, syntax (/ ˈ s ɪ n t æ k s / SIN-taks) [1] [2] is the study of how words and morphemes combine to form larger units such as phrases and sentences.Central concerns of syntax include word order, grammatical relations, hierarchical sentence structure (constituency), [3] agreement, the nature of crosslinguistic variation, and the relationship between form and meaning ().
Versions of non-acronym abbreviations that do not end in full points (periods) are more common in British than North American English and are always [b] abbreviations that compress a word while retaining its first and last letters (i.e., contractions: Dr, St, Revd) rather than truncation abbreviations (Prof., Co.). That said, US military ranks ...
A nominal group is widely regarded as synonymous with noun phrase in other grammatical models. [1] [2] However, there are two major differences between the functional notion of a nominal group and the formal notion of a noun phrase that must be taken into account.
