Teaching Vocabulary

Vocabulary can be roughly defined as the word we teach in the foreign language.However,there are many new items of vocabulary which combine more than one words. phrasal verbs like- put on, looking forward to etc.and idioms like as a matter of fast, as the crow flies etc.Consist of more than one words but they are counted as single item science they convey single meaning. Therefore, the better way of conving these conditions is to say- a vocabulary is the item we teach in the foreign language.
While teaching vocabulary , the teacher should teach the pronunciation and spelling, different forms used in different contexts. Along with the base form , we might provide the ideas of past form to find out whether the verb is regular or irregular and we might note whether it is transitive or intransitive. We can also give an ideas for preposition it takes and provide the ideas of singular and plural forms. Beside these, the idea of word combination should also be taught to the students.
It may be worth teaching which words go together while teaching new items for e.g make or take decision or conclusion, throw a ball/toss a coin. Vocabulary should be taught from different angle. We should teach it's denotation(direct) meaning, connotation (indirect) meaning and it's appropriateness of using in the given context.
It is important to teach synonyms,antonyms,hyponyms(dog is the hyponyms of animal) and mother tongue equivalence.
It is also necessary to teach word formation of the items, common prefixes and sufrfixes which goes to the particular items.
