English grammar – Comparatives and Superlatives basic introduction:

Adjectives and adverbs can be used to compare similarities or differences amongst things, people, places, actions… When 2 things are compared we use the comparative form; when one thing is compared to a full category, we use the superlative form. These forms, as you will see, depending on the number of syllables in the adjective or adverb. There are also other ways to make comparisons using other expressions.

Other comparatives expressions

There are other ways to express the idea of comparison. Look at the following structures:

-‘As + adjective/adverb + as’ (comparative of equality)

  • These products aren’t as efficient as the other brand’s products.
  • They walked as quietly as they could in order not to interrupt the filming.

-‘One of the –est things’ (always followed by a plural)

  • That book you lent me is one of the best stories I’ve read in years!

-‘the –er, the –er’

  • The slower you pay, the longer you wait for delivery.

‘less + adjective + than’ (comparative of inferiority)

  • The students are less motivated after their exams than how they were atthe beginning of the school year.

Things to look out for

> Remember that ‘as’ is used twice in the sentence (see examples above).

> Comparative sentences use ‘than’, but ‘than’ is not used with ‘as’.

> ‘The’ is used with superlative sentences EXCEPT in the example given in ‘other comparative expressions.

> We say ‘the same as’ (NOT ‘than’): Her suitcase was the same as mine.
