Teaching Vocabulary refers to a set of words and phrases that are taught or introduced to students in order for them to improve their language skills, particularly in reading, writing, speaking, and listening. It is an essential part of the learning process as it helps learners understand new concepts, ideas, and information more easily by providing them with the necessary tools to express themselves accurately and effectively. Teaching Vocabulary involves various techniques such as word association, context clues, flashcards, vocabulary games, and quizzes that help students internalize new words and use them in their daily communication.
