Vv UNIT TWO Language meaning and definition Language: it is asocial entity or phenomena composed of standardized uses of word, phrases sentences, symbols, signs, gesture, that could be shared, exchanged, communicated through speech or written forms to reflect feelings, understanding and desires. For our purpose, two linguistic functions are particularly important: To convey information and To express or evoke feelings. Cognitive meaning of terms It is a terminology that convey information Used to refer contents of reality of some thing They are objective and could be judged as true or false Example: Abebe is a teacher. There are different historical place Ethiopia Animal killing is a practice which predates modern history. both ancient and modern people kill animal for different reason fore example to eat meat to use their skin horn to produce medisin.....\ete These two statements are intended primarily to convey information. They are said to have cognitive meaning. Emotive meaning They are terminologies that express feelings, valuing emotions, prejudice, attitude, sensation Emotive meanings are’subjective. They could not be judged as true or false Example: It is shameful, you should stop it. Her beauty is beyond every ones imagination The president concluding an interesting conversation. Animal killing is a savage act which a cruel | person parson slaughter an innocent animal for his selfish interest. such person are immoral to consider as a human At least in part these’ statements express or evoke feelings and are said to have emotive meaning. Logic is concerned chiefly with cognitive meaning, because emotive meanings are distracte the whole reality. A value claim is a claim that something is good, bad, right, wrong, or better, worse, more important or less important than some other thing. 2.2 The Intension and Extension of Terms The main task of logic is the evaluation of arguments. The study of meaning and definition is closely related to the main task of logic. The basic units of any ordinary language are words. Our main concern in this chapter, however, is not with words in general but with terms. A term is any word or arrangement of words that may serve as the subject of a statement. Terms consist of proper names, common names, and descriptive phrases. Term is any word or a group of words that can serve as the subject term of the sentence . Examples: Proper names ; name of person or country Napoleon The United States
