I’m sure most of you know the comparative form of adjectives:

This class is bigger than that class.

This painting is more beautiful than that painting.

But did you know that in English sometimes a comparative form is repeated for emphasis or to show a continuing action:

Cell phones keep getting smaller and smaller. (emphasizes a continuing trend)

The weather got worse and worse throughout the night. (emphasizes the passage of time)

The questions on the exam became more and more difficult. (emphasizes the progression of the exam)

Notice that that if the adjective ends in -er or has an irregular form (Ex. worse) the entire adjective is repeated. For longer adjectives, “more” is repeated, but not the adjective itself.
