I. INTRODUCTION TO COMPARATIVES

2. Comparatives for Showing Similarities and Differences

2.2 Comparative and Superlative Adjectives

2.2.1 One-Syllable Adjectives

For one-syllable adjectives, we use the comparative suffix '-er' and the superlative suffix the + '-est'. Note that the article 'the' is used with the superlative form because the possible selection is limited to only one thing, person, or animal.

Examples

fast – faster – the fastest

high – higher – the highest

low – lower – the lowest

soon – sooner – the soonest

hard – harder – the hardest

late – later – the latest

deep – deeper – the deepest

wide – wider – the widest

young – younger – the youngest

Examples in context:

The Empire State Building was once the tallest building in the world at 443 meters, but that record would eventually fall to the much taller Jeddah Tower, which stands at 1-kilometer high.

The lowest point in the United States is Death Valley at 86 meters below sea level, but the Dead Sea is much lower, and, at 414 meters below sea level, it is the lowest point in the world.

At around 8,850 meters (29,000 feet), most people think that Mount Everest is the tallest mountain in the world; however, the world is not completely round. It bulges at the equator, so the earth is wider at the equator. So, if you are standing at the highest point on Mount Chimborazo in Ecuador, you are actually 2,070 meters farther from the center of the earth than you would be if you stood at the top of Mount Everest.

For a brief time, the newly constructed Port Mann Bridge in Metro Vancouver, Canada, at 65 meters, was the widest of its kind in the world.

Kind of Adjective Comparative Form Superlative Form
Ordinary adjectives Add '-er' as a suffix to the word.
low – lower
Add '-est' as a suffix to the word.
low – lowest
Adjectives that end in '-e' Simply add '-r' to the word. The word already has '-e' at the end.
wide – wider
Add '-st' as a suffix to the word. Again, the word already has '-e' at the end.
wide – widest
Adjectives that end with one vowel and one consonant Double the final consonant and add '-er'
thin – thinner
Double the final consonant and add '-est'
big – biggest
hot – hottest
thin – thinnest
Some one-syllable adjectives have irregular forms. good – better – the best
bad – worse – the worst
little – less – the least
much – more – the most
far – farther – the farthest OR far – further – the furthest
old – older – the oldest OR old – elder – the eldest

2.2.2 Two-Syllable Adjectives

Most two-syllable adjectives use the comparative 'more' or 'less' and the superlative 'most' or 'least' before the adjective.

Examples

common – more common – most common

famous – more famous – most famous

* Be careful not to use the suffixes '-er' or '-est' together with 'more' and 'most'. Example: She is more happier happy.

However, some two-syllable adjectives can use either '-er/-est' or 'more/most'. These include:

  • simple – simpler – simplest OR simple – more simple – most simple
  • happy – happier – happiest OR happy – more happy – most happy
  • clever – clever – cleverest OR clever – less clever – least clever
  • able – abler – ablest OR able – more able – most able
  • quiet – quieter – quietest OR quiet – more quiet – most quiet
  • gentle – gentler – gentlest OR gentle – less gentle – least gentle

There seem to be regional or national differences in the way these are used.

Some participles with two syllables can be used in the comparative and superlative forms. They are formed in the same way as adjectives; however, for the comparative, sometimes we use an adjective clause.

  • Passive Participle: eaten – more eaten – most eaten. (The most eaten food is rice.) OR The food that is eaten more is rice. (adjective clause)
  • Active Participle: alluring – more alluring – most alluring
2.2.2.1 Spelling of Two-Syllable Adjectives that End in '-y'

Change the '-y' to '-i' and add '-er' or '-est'.

Examples

busy – busier – busiest

noisy – noisier – noisiest

petty – pettier – pettiest

lousy – lousier – lousiest

Examples in Context:

The most intelligent person in the world was Albert Einstein, but the most clever might have been the escape artist Harry Houdini.

The busiest airport in the world used to be Chicago's O'Hare airport.

One of the most common mistakes that people make when learning English is with subject-verb agreement; however, it is not actually a mistake in choosing the wrong verb. The more common reason is that they make a mistake with the fact that a noun is 'non-count' and is therefore singular.

Can the quietest person in the room be more annoying than the loudest person?

2.2.3 Adjectives with Three Syllables or More

All adjectives with three syllables or more use more and less for the comparative and most/least for the superlative. More/less and most/least are followed by the adjective. Again, be sure not to combine these words with '-er' and '-est'. For example, don't use 'more intelligenter' or 'most intelligentest'.

Examples

important – more important – most important

intelligent – more intelligent – most intelligent

visible – more visible – most visible

Some participles with three syllables can be used in the comparative and superlative forms. They are formed in the same way as adjectives.

Examples

interesting – more interesting – most interesting

fascinating – more fascinating – most fascinating

Study Tip: Visual Processing Power

What you see actually takes up a large part of your brain processing power. So, if you are learning something, try closing your eyes. People often do this subconsciously when they are focusing on something. Make it a conscious practice when you are learning. If you are reading, and of course you need your eyes to read, take away any other visual distractions. Clean up your desk and remove clutter from your learning area. Have you ever found that a clean room is more relaxing? It is because it takes up less of our focus, and it helps us to relax.

In the same way that you declutter your desk of distractions, also declutter the information that you are learning. Take out anything that is unnecessary at the moment. You can always connect it later.
