26.1 Compare two things
| Learn | Simple English |
|---|---|
| Rule | Use a comparative to say how things differ. Use than when you name the other thing. |
| Pattern | Bigger than. More useful than. Less heavy than. |
| Example | This box is larger than that one. |
| Why | You can also say I need a larger box when the other box is already clear. |
26.2 Build the comparison
| Learn | Simple English |
|---|---|
| Rule | Many short adjectives add -er and -est. Longer ones often use more and most. Some common words change completely. |
| Pattern | Small → smaller → smallest. Good → better → best. |
| Example | This bag is smaller. This tool is more useful. |
| Why | Learn spelling changes too: happy → happier → happiest. Do not say more smaller. |
26.3 Choose one from a group
| Learn | Simple English |
|---|---|
| Rule | Use a superlative to choose the highest or lowest in a group. The often comes before it. A possessive can replace the. |
| Pattern | The biggest. The most useful. My best. |
| Example | This is the largest box of the three. She is my best friend. |
| Why | Say my best friend, not the my best friend. |
26.4 The same or different?
| Learn | Simple English |
|---|---|
| Rule | Use as…as for equal qualities. Use not as…as for a difference. Much can make a comparative stronger. |
| Pattern | As + adjective + as. Much + comparative. |
| Example | This box is as heavy as that one. The new route is much shorter. |
| Why | As heavy as means equal weight. Much shorter means a large difference in length. |
26.5 Compare the patterns side by side
| Quality | Comparative | Superlative |
|---|---|---|
| small | smaller | smallest |
| useful | more useful | most useful |
| happy | happier | happiest |
| good / bad | better / worse | best / worst |
