This is from Part 3 – Word Formation, where you take a root word (like possible) and transform it to fit the sentence.
Cambridge loves testing prefixes like im-, in-, un-, dis-, and ir-.
They all mean “not,” but which one you use depends on the first letter and sound of the base word.
Common patterns:
- im- before p or m → impossible, impatient
- in- before most consonants → invisible, incorrect
- ir- before r → irregular
- il- before l → illegal
💡 Pro tip:If you’re not sure, say it out loud.“Unpossible” sounds wrong instantly. Your ear often knows before your brain does.
✅ Hint: This one starts with p.
