Antonyms for ISSB — 200 Most Tested Opposite Words With Examples

I still remember one student who was very good at synonyms but kept losing marks in antonyms.

The word was “ancient”. The options were old, modern, historic, antique. He quickly marked “old” because he had learned that ancient means old. But the question was asking the opposite, so the correct answer was modern.

That is the most common mistake in ISSB verbal intelligence preparation. Students read the word, remember its meaning, and forget that the test is asking for the opposite.

Antonyms are usually easy marks if you train your mind properly. You don’t need fancy English. You need quick recognition. In ISSB-style MCQs, you may get only a few seconds to choose the opposite word, so revision matters more than overthinking.

This guide contains 200 important antonyms for ISSB with simple examples. I have kept the examples short because students need quick revision, not dictionary-style explanations.

How to Learn Antonyms for ISSB

Before you start the list, remember these three rules:

• Read the instruction carefully. If the question asks “opposite,” don’t mark the synonym by mistake.
• Learn word pairs. For example: accept/reject, brave/cowardly, ancient/modern.
• Use examples. A word sticks better when you see it in a sentence.

Also, some words have more than one opposite depending on context. For example, light can mean “not heavy” or “not dark.” So always look at the sentence if context is given.

Common Antonym Traps in ISSB Tests

Some words confuse students because their opposite changes with meaning. Keep these in a separate notebook.

Light	Not dark	Dark
Light	Not heavy	Heavy
Close	Near	Far
Close	Shut	Open
Right	Correct	Wrong
Right	Direction	Left

This is why I always tell students to read the full sentence if the question gives context. Don’t answer only by habit.

Final Teacher’s Advice

Antonyms are one of the easiest ways to improve your ISSB verbal score, but only if you practice them properly.

Read the word. Understand the meaning. Learn the opposite. Use it in a sentence. Then test yourself under time pressure.

The real test is not whether you can remember the word after reading it once. The real test is whether you can identify the opposite in five seconds when the clock is running.

Start with these 200 words. Revise them for a week. Keep a small mistake list. You’ll notice your speed improving very quickly.

Disclaimer: This antonym list is prepared for general ISSB-style verbal intelligence and English vocabulary practice. Exact words may vary by test, batch, and official paper pattern. Some words may have different opposites depending on sentence context, so always read the question carefully before selecting an answer. 🇵🇰
