What aspect of English is emphasized in the vocabulary section?

The vocabulary section emphasizes synonyms, antonyms, and contextual usage of words because it focuses on understanding how words relate to one another and how they fit into different contexts. This aspect is crucial for building a robust vocabulary as it enables learners to recognize different shades of meaning and use words effectively in various situations. By understanding synonyms, learners can expand their vocabulary and express themselves more precisely. Antonyms provide insights into contrasting ideas, which enhances comprehension and enriches communication. Additionally, contextual usage helps learners grasp how words function in sentences and the nuances that change their meanings based on context. This comprehensive approach is fundamental for language acquisition and practical use of English.
