WordsWhat you are actually practicing
English compares with four rules and a short list of exceptions. Most adjectives add -er and -est. Short vowel words double the final consonant: big → bigger → biggest. Words ending in -y change it to -i: happy → happier → happiest. Long adjectives take more and most.
Then there are the words so common they broke the pattern: good → better → best, bad → worse → worst.
How the game works
You are shown an adjective and its comparative, and four superlatives. Pick the correct one. A wrong pick reveals it immediately.
Easy uses the most familiar adjectives. Medium widens the set. Hard uses the full list, including the irregulars.
The rules worth knowing
Add -est: large → largest, busy → busiest.
Double the consonant: big → bigger → biggest, hot → hottest, thin → thinnest, wet → wettest.
-y becomes -i: happy → happiest, easy → easiest, dry → driest, busy → busiest.
Irregular: good → better → best, bad → worse → worst, many → more → most.
Strategies that actually raise your score
Check the comparative you were given. It already tells you which rule the adjective follows: if it doubled the consonant for -er, it doubles again for -est.
Reject the comparative. It is always on screen as a distractor. bigger is not the superlative of anything — if you picked it, you stopped one step early.
Watch the doubled letters. bigest and hotest look plausible and are wrong; the consonant must double. This is the single most frequent spelling error in the whole topic.
Trust the irregulars. goodest and baddest do not exist in standard English. When you see a regular form built on an irregular adjective, it is a distractor.
