Second Grade English: Comparative & Superlative Adjectives (-er, -est)

When you look at objects in the world, you often notice that they are not all equal in their qualities. One pine tree might be tall, but the oak tree next to it might have even greater height, and the redwood at the end of the forest might surpass every other tree in the entire park! To express these differences in degree, the English language uses comparative and superlative adjectives. In this chapter, you will master the rules for comparing two items using the comparative suffix -er, and comparing three or more items using the superlative suffix -est.

The Three Degrees of Adjectives

Every descriptive adjective can exist in three distinct degrees: positive, comparative, and superlative.

+-----------------------------------------------------------------+
|                  THE THREE COMPARATIVE DEGREES                  |
+-----------------------------------------------------------------+
|                                                                 |
|   1. POSITIVE DEGREE (Base Quality, 1 item):                    |
|      "The rabbit is FAST."                                      |
|                                                                 |
|   2. COMPARATIVE DEGREE (Compares EXACTLY 2 items):             |
|      "The horse is FASTER than the rabbit."  (Add -ER)          |
|                                                                 |
|   3. SUPERLATIVE DEGREE (Compares 3 OR MORE items):             |
|      "The cheetah is the FASTEST of all three." (Add -EST)      |
|                                                                 |
+-----------------------------------------------------------------+

The Number Rule

This is the golden key to choosing between -er and -est: If you are comparing TWO items -> Use -er (Comparative). If you are comparing THREE OR MORE items -> Use -est (Superlative).

Spelling Rules for Adding -er and -est

Adding -er and -est follows three systematic spelling adjustments based on the base adjective's ending letters.

+-----------------------------------------------------------------+
|                 SPELLING RULES FOR -ER AND -EST                 |
+-----------------------------------------------------------------+
|  Base Adjective | Rule Applied        | Comparative | Superlative|
+-----------------+---------------------+-------------+------------+
|  tall (regular) | Just add ending     | taller      | tallest    |
|  wide (ends e)  | Drop silent e       | wider       | widest     |
|  big (short CVC)| Double final cons.  | bigger      | biggest    |
|  heavy (ends y) | Change y to i       | heavier     | heaviest   |
+-----------------------------------------------------------------+

Rule 1: The Standard Addition

For most short adjectives, simply attach the endings: small -> smaller -> smallest bright -> brighter -> brightest quick -> quicker -> quickest

Rule 2: Drop the Silent E

If an adjective ends in silent 'e', drop the 'e' before adding -er or -est: brave -> braver -> bravest cute -> cuter -> cutest large -> larger -> largest

Rule 3: The CVC Doubling Rule (1-1-1 Rule)

If an adjective has 1 syllable, 1 short vowel, and ends in 1 consonant, double that consonant: hot -> hotter -> hottest sad -> sadder -> saddest wet -> wetter -> wettest

Rule 4: Change Y to I

If an adjective ends in consonant + y, change the y to i before adding the ending: happy -> happier -> happiest funny -> funnier -> funniest sunny -> sunnier -> sunniest

Irregular Comparison Champions: Good and Bad

A few very famous adjectives do not add -er or -est at all; they transform into completely irregular words! Look at good: You never say "gooder" or "goodest!" One apple is good. The peach is better. The strawberry is the best! Look at bad: You never say "badder" or "baddest!" A cold is bad. The flu is worse. Pneumonia is the worst!

Practice Exercises

Exercise 1: Fill in the correct comparative (-er) and superlative (-est) forms for each base adjective: cold, warm, tiny, mad.

Exercise 2: Choose the correct word in parentheses: "Between Maya and her brother, Maya is the (taller / tallest)." "Out of all thirty students in the class, Leo ran the (faster / fastest)."

Exercise Solutions

Solution to Exercise 1: For cold: colder, coldest. For warm: warmer, warmest. For tiny: tinier (change y to i), tiniest (change y to i). For mad: madder (double d), maddest (double d).

Solution to Exercise 2: In the first sentence, the correct choice is taller because exactly two people are being compared (Maya and her brother). In the second sentence, the correct choice is fastest because thirty students (more than two) are being compared.
