A gender role is a set of social and behavioral norms that are generally considered appropriate for either a man or a woman in a social or interpersonal relationship. There are differences of opinion as to which observed differences in behavior and personality between genders are entirely due to innate personality of the person and which are due to cultural or social factors, and are therefore the product of socialization, or to what extent gender differences are due to biological and physiological differences.
Gender roles differ according to cultural-historical context, and while most cultures express two genders, some express more. Androgyny, for example, has been proposed as a third gender. Others societies have been claimed to have more than five genders, and some non-Western societies have three genders – man, woman and third gender. Gender expression refers to the external manifestation of one's gender identity, through masculine, feminine, or gender-variant or gender neutral behavior, clothing, hairstyles, or body characteristics.
In linguistics, grammatical gender is a system of noun classification present in approximately one fourth of the world's languages. In these languages, every noun inherently carries one value of the grammatical category called gender; the values present in a given language (of which there are usually two or three) are called the genders of that language. According to one definition: "Genders are classes of nouns reflected in the behaviour of associated words."
Common gender divisions include masculine and feminine; masculine, feminine and neuter; or animate and inanimate. In a few languages, the gender assignation of nouns is solely determined by their meaning or attributes, like biological sex, humanness, animacy. However, in most languages, this semantic division is only partially valid, and many nouns may belong to a gender category that contrasts with their meaning (e.g. the word "manliness" could be of feminine gender). In this case, the gender assignation can also be influenced by the morphology or phonology of the noun, or in some cases can be apparently arbitrary.
In linguistics, morphology is the identification, analysis and description of the structure of a given language's morphemes and other linguistic units, such as root words, affixes, parts of speech, intonation/stress, or implied context (words in a lexicon are the subject matter of lexicology). Morphological typology represents a method for classifying languages according to the ways by which morphemes are used in a language—from the analytic that use only isolated morphemes, through the agglutinative ("stuck-together") and fusional languages that use bound morphemes (affixes), up to the polysynthetic, which compress many separate morphemes into single words. (One of the definitions for Morphology).]clarification needed[
While words are generally accepted as being (with clitics) the smallest units of syntax, it is clear that in most languages, if not all, words can be related to other words by rules (grammars). For example, English speakers recognize that the words dog and dogs are closely related—differentiated only by the plurality morpheme "-s", which is only found bound to nouns, and is never separate. Speakers of English (a fusional language) recognize these relations from their tacit knowledge of the rules of word formation in English. They infer intuitively that dog is to dogs as cat is to cats; similarly, dog is to dog catcher as dish is to dishwasher, in one sense. The rules understood by the speaker reflect specific patterns, or regularities, in the way words are formed from smaller units and how those smaller units interact in speech. In this way, morphology is the branch of linguistics that studies patterns of word formation within and across languages, and attempts to formulate rules that model the knowledge of the speakers of those languages.
A social issue (also called a social problem or a social situation) is an issue that relates to society's perception of a person's personal lives. Different cultures have different perceptions and what may be "normal" behavior in one society may be a significant social issue in another society. Social issues are distinguished from economic issues. Some issues have both social and economic aspects, such as immigration. There are also issues that don't fall into either category, such as wars.
Thomas Paine, in Rights of Man and Common Sense, addresses man's duty to "allow the same rights to others as we allow ourselves". The failure to do so causes the birth of a social issue.
The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve several billion users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW), the infrastructure to support email, and peer-to-peer networks.
Most traditional communications media including telephone, music, film, and television are being reshaped or redefined by the Internet, giving birth to new services such as voice over Internet Protocol (VoIP) and Internet Protocol television (IPTV). Newspaper, book and other print publishing are adapting to website technology, or are reshaped into blogging and web feeds. The Internet has enabled and accelerated new forms of human interactions through instant messaging, Internet forums, and social networking. Online shopping has boomed both for major retail outlets and small artisans and traders. Business-to-business and financial services on the Internet affect supply chains across entire industries.
