ENGAGE

Guess without a dictionary

The path was impassable: fallen trees blocked every route and the mud swallowed our boots. You have probably never used the word impassable, yet the sentence has already told you what it means.

Think about it

  • Which words in the sentence gave the meaning away?
  • What does the prefix im- usually do to a word?

  • The judge was impartial, favouring neither side.
