One of the most important prerequisites for effective communication is a wide vocabulary. A wide vocabulary facilitates and sharpens one’s oral and written skills. In this regard, Primary Level Vocabulary And Usage, a series of 6 books, has been specially designed to cater to the needs of primary level students. A thematic approach has been adopted where new words are introduced through an interesting story. This is followed by a series of practical exercises aimed at consolidating the students' knowledge of and their ability to use the newly-acquired vocabulary. The books aim to equip the students with a wide vocabulary that will greatly enhance their listening, speaking, reading and writing abilities, thereby helping them to achieve a reasonable level of proficiency in the English language.
