In this video lesson, you will learn how to use the words buy and purchase. Vocabulary represents one of most important skills necessary for teaching and learning a foreign language. It is the basis for the development of all the other skills: reading comprehension, listening comprehension, speaking, writing, spelling and pronunciation. Vocabulary is the main tool for the students in their attempt to use English effectively. When confronted with a native English speaker, when watching a movie without subtitle or when listening to a favorite English song, when reading a text or when writing a letter to a friend, students will always need to operate with words. ‪@learnenglishwithnanncy‬
