TYPICAL ERROR Hannah and Samantha had a race to see who would get into the school relay team and Samantha was the fastest.
CORRECTION Hannah and Samantha had a race to see who would get into the school relay team and Samantha was the faster.
EXPLANATION If we wish to say how fast someone can run, we might say:
Ben is a fast runner, Lauren is a faster runner but Dan is the fastest runner.
The words fast, faster and fastest are called the three degrees of comparison of the adjective fast: The adjective itself (fast) is the first degree, faster is the second degree (comparing two things) and fastest is the third degree (comparing three or more things).
The three degrees of comparison are also called the positive degree, the comparative degree and the superlative degree.
In each of these sentences fix the adjective where the wrong degree of comparison has been used.
