Politics (from Greek politikos "of, for, or relating to citizens") as a term is generally applied to the art or science of running governmental or state affairs, including behavior within civil governments, but also applies to institutions, fields, and special interest groups such as the corporate, academic, and religious segments of society. It consists of "social relations involving authority or power" and to the methods and tactics used to formulate and apply policy.

Modern political discourse focuses on democracy and the relationship between people and politics. It is thought of as the way we "choose government officials and make decisions about public policy".

The word politics comes from the Greek word Πολιτικά (politika), modeled on Aristotle's "affairs of the city", the name of his book on governing and governments, which was rendered in English mid-15 century as Latinized "Polettiques". Thus it became "politics" in Middle English c. 1520s (see the Concise Oxford Dictionary). The singular politic first attested in English 1430 and comes from Middle French politique, in turn from Latin politicus, which is the latinisation of the Greek πολιτικός (politikos), meaning amongst others "of, for, or relating to citizens", "civil", "civic", "belonging to the state", in turn from πολίτης (polites), "citizen" and that from πόλις (polis), "city".

Information, in its most restricted technical sense, is a sequence of symbols that can be interpreted as a message. Information can be recorded as signs, or transmitted as signals. Information is any kind of event that affects the state of a dynamic system. Conceptually, information is the message (utterance or expression) being conveyed. This concept has numerous other meanings in different contexts. Moreover, the concept of information is closely related to notions of constraint, communication, control, data, form, instruction, knowledge, meaning, mental stimulus, pattern, perception, representation, and especially entropy.

The English word was apparently derived from the Latin stem (information-) of the nominative (informatio): this noun is in its turn derived from the verb "informare" (to inform) in the sense of "to give form to the mind", "to discipline", "instruct", "teach": "Men so wise should go and inform their kings." (1330) Inform itself comes (via French informer) from the Latin verb informare, to give form, to form an idea of. Furthermore, Latin itself already contained the word informatio meaning concept or idea, but the extent to which this may have influenced the development of the word information in English is not clear.
