Before closing this book's antonym section, run through the full word list once more and say each pair out loud without looking at the table — Sacred/Profane, Scanty/Ample, Stringent/Lax, and so on down to Zenith/Nadir. This kind of active recall, rather than passive re-reading, is what actually moves these sixty-eight words from short-term to long-term memory before exam day. As a final check, revisit any pair you hesitated over even once during the two quizzes in this chapter — those are the exact words most likely to reappear as distractors in your next mock test.

Finally, remember that antonym questions in the actual exam are rarely presented as a bare word-to-word match. More often, you will see the headword embedded in a full sentence, with four answer choices offering different possible opposites, and your task is to pick the one that fits the sentence's meaning precisely, not merely a dictionary opposite pulled from memory. Practising with sentences, as this chapter has done throughout, prepares you far better than memorising isolated word pairs ever could. With this chapter, the full antonym coverage from A to Z in this book is complete; the next chapters move on to one-word substitutions.
