What you’ll learn

Three Steps of ComparisonIdentify the three degrees of comparison — plain, comparative, and superlative — and when each is used.Every describing word has three forms: plain describes one thing, comparative compares two, and superlative tops a group of three or more. The endings grow (nothing, -er, -est) as you climb.
Comparative: Comparing TwoUse the comparative form to compare exactly two things, recognizing 'than' as its signal word.The comparative weighs two things against each other and usually pairs with 'than.' If 'than' fits naturally after the word, the comparative is the right choice.
Superlative: Top of the GroupUse the superlative form to pick the top of a group of three or more, recognizing 'the' as its signal word.The superlative crowns one item out of many and almost always follows 'the.' The -est ending or the 'most' form does the crowning.
The -er / -est ToolkitBuild comparative and superlative forms of short words by adding -er/-est, applying the spelling rules.Short words take -er and -est. Three spelling rules cover most cases: drop a silent e, double a final consonant after a short vowel, and change a final y to i.
The more / most ToolkitBuild comparative and superlative forms of longer words using 'more' and 'most.'Longer words (usually three or more syllables) use the helper words 'more' and 'most' instead of endings, because -est would sound clumsy. The adjective itself stays unchanged.
The RebelsRecall the common irregular comparison words that follow neither toolkit.A few very common words are irregular: good/better/best, bad/worse/worst, far/farther/farthest, many/more/most. They must be memorized rather than built by rule.
Never Use Both ToolkitsAvoid double comparisons by using only one comparison tool per word.You add an ending OR use more/most — never both. Forms like 'more bigger' or 'most tallest' double the comparison and are incorrect; pick one toolkit and stop.

Questions this course answers

Which sentence correctly uses a superlative?

'Smallest' tops a group of three, and 'the' signals a superlative. It picks one winner out of many.

You are comparing exactly two things. Which form and signal word should you reach for?

Two things call for the comparative, and 'than' is its usual partner: 'taller than,' 'faster than.'

Why does 'the' almost always appear before a superlative like 'the fastest'?

A superlative names the single top of a group, so 'the' marks that one-and-only winner.

Which spelling rule turns 'big' into 'bigger'?

'Big' ends in a short vowel then a consonant, so you double the g to keep the vowel short: bigger, biggest.

Why do we say 'more beautiful' instead of 'beautifuler'?

Longer adjectives take the helper words more/most. Gluing -er onto a long word sounds wrong, so English uses 'more.'

What is wrong with 'This test was more harder than the last'?

'Harder' already compares; adding 'more' doubles it. Use one toolkit only: 'harder than' is correct.
