Re-write the following sentences according to the instructions given after each. Make other changes that may be necessary, but do not change the meaning of each sentence.
Greenland is the largest island in the world. (Re-write using 'larger')
Topic: Degrees of comparison — superlative to comparative
Answer
Greenland is larger than any other island in the world.
Converting a SUPERLATIVE into the COMPARATIVE follows a fixed formula, and it is worth learning as a template: Superlative: X is the LARGEST island in the world. Comparative: X is LARGER THAN ANY OTHER island in the world.
The two words that matter are ANY OTHER. Writing "larger than any island in the world" would be wrong, because Greenland is an island and cannot be larger than itself. The word OTHER excludes it from the comparison.
The third form of the same statement, often asked as an alternative: Positive: No other island in the world is as large as Greenland.
Learn all three together; papers ask for any one of them.
