16. What is the evocative function?
The “evocative function” is the use of language to create certain feelings in the hearer. Its aim is , for example, to amuse, startle, antagonize, soothe, worry or please. Jokes(not practical jokes, though) are supposed to amuse or entertain the listener; advertising to urge customers to purchase certain commodities; propaganda to influence public opinion. Obviously, the expressive and the evocative functions often go together, i.e., you may express, for example, your personal feelings about a political issue but end up by evoking the same feeling in, or imposing it on, your listener. That’s also the case with the other way round.

17. What is the performative function?
This means people speak to “do things” or perform actions. On certain occasions the utterance itself as an action is more important than what words or sounds constitute the uttered sentence. The judge’s imprisonment sentence, the president’s war or independence declaration, etc., are performatives.

18. What is linguistics?
“Linguistics” is the scientific study of language. It studies not just one language of any one society, but the language of all human beings. A linguist, though, does not have to know and use a large number of languages, but to investigate how each language is constructed. He is also concerned with how a language varies from dialect to dialect, from class to class, how it changes from century to century, how children acquire their mother tongue, and perhaps how a person learns or should learn a foreign language. In short, linguistics studies the general principles whereupon all human languages are constructed and operate as systems of communication in their societies or communities.

19. What makes linguistics a science?
Since linguistics is the scientific study of language, it ought to base itself upon the systematic, investigation of language data which aims at discovering the true nature of language and its underlying system. To make sense of the data, a linguist usually has conceived some hypotheses about the language structure, to be checked against the observed or observable facts. In order to make his analysis scientific, a linguist is usually guided by four principles: exhaustiveness, consistency, and objectivity. Exhaustiveness means he should gather all the materials relevant to the study and give them an adequate explanation, in spite of the complicatedness. He is to leave no linguistic “stone” unturned. Consistency means there should be no contradiction between different parts of the total statement. Economy means a linguist should pursue brevity in the analysis when it is possible. Objectivity implies that since some people may be subjective in the study, a linguist should be (or sound at least) objective, matter-of-face, faithful to reality, so that his work constitutes part of the linguistics research.

20. What are the major branches of linguistics?
The study of language as a whole is often called general linguistics. But a linguist sometimes is able to deal with only one aspect of language at a time, thus the arise of various branches: phonetics, phonology, morphology, syntax, semantics, pragmatics, sociolinguistics, applied linguistics, psycholinguistics etc.
21. What are synchronic and diachronic studies?
The description of a language at some point of time (as if it stopped developing) is a synchrony study (synchrony). The description of a language as it changes through time is a diachronic study (diachronic). An essay entitled “On the Use of THE”, for example, may be synchronic, if the author does not recall the past of THE, and it may also be diachronic if he claims to cover a large range or period of time wherein THE has undergone tremendous alteration.

22. What is speech and what is writing?
No one needs the repetition of the general principle of linguistic analysis, namely, the primacy of speech over writing. Speech is primary, because it existed long long before writing systems came into being. Genetically children learn to speak before learning to write. Secondly, written forms just represent in this way or that the speech sounds: individual sounds, as in English and French as in Japanese. In contrast to speech, spoken form of language, writing as written codes, gives language new scope and use that speech does not have. Firstly, messages can be carried through space so that people can write to each other. Secondly, messages can be carried through time thereby, so that people of our time can be carried through time thereby, so that people of our time can read Beowulf, Samuel Johnson, and Edgar A. Poe. Thirdly, oral messages are readily subject to distortion, either intentional or unintentional, while written messages allow and encourage repeated unalterable reading. Most modern linguistic analysis is focused on speech, different from grammarians of the last century and theretofore.
