Superlative Adjectives Worksheets - 15 Worksheets Library - Free Printable

To find the correct superlative adjective for each row, we need to look at how many syllables are in the base word and check for any spelling changes.

Here is the step-by-step breakdown:

1. angry: This is a two-syllable word ending in "y". We change the "y" to "i" and add "-est".
* Correct choice: angriest

2. lazy: This is a two-syllable word ending in "y". We change the "y" to "i" and add "-est".
* Correct choice: laziest

3. serious: This is a three-syllable word. Long words usually take "most".
* Correct choice: most serious

4. sad: This is a one-syllable word with a short vowel sound. We double the last letter "d" and add "-est".
* Correct choice: saddest

5. comfortable: This is a four-syllable word. It is too long to add "-est", so we use "most".
* Correct choice: most comfortable

6. wonderful: This is a three-syllable word. We use "most".
* Correct choice: most wonderful

7. frequent: This is a two-syllable word. While some two-syllable words can go either way, "most frequent" is the standard and most common form.
* Correct choice: most frequent

8. talented: This is a three-syllable word. We use "most".
* Correct choice: most talented

9. crunchy: This is a two-syllable word ending in "y". We change the "y" to "i" and add "-est".
* Correct choice: crunchiest

10. stable: This is a two-syllable word ending in "e". We just add "-st".
* Correct choice: stablest (Note: While "most stable" is also very common in modern English, "stablest" is the grammatically formed superlative often found in these types of worksheets. However, looking at the pattern of the other errors like "furnishest", this worksheet seems to test specific rules. Let's re-evaluate "stable". Usually, adjectives ending in -le just add -st. So *stablest* is correct morphologically. But wait, is it? Actually, "most stable" is frequently preferred. Let's look at the other options. "Furnished" -> "most furnished". "Serious" -> "most serious". The worksheet includes incorrect forms like "seriousest" and "furnishest" to trick you. Between "most stable" and "stablest", both are used, but "most stable" is safer for longer sounding words. However, "simple" becomes "simplest". "Stable" follows the same rule. Let's stick with the morphological rule for now: stablest. *Self-correction*: In many school contexts, if a word ends in -le, you drop the e and add -est? No, you keep the e and add -st. Simple -> simplest. Stable -> stablest. Okay.)

*Let's double check standard usage.* Actually, for "stable", most stable is often considered more natural, but stablest is the direct superlative form. Given the other clear rules (y->i, double consonant, long words use 'most'), let's look at the distractors. "Furnishest" is clearly wrong. "Talentedest" is clearly wrong. "Stablest" is a valid word. I will select stablest as it follows the mechanical rule for adjectives ending in -le, similar to simple/simplest.

11. furnished: This is a participle acting as an adjective. These almost always use "most". Also, "furnishest" is not a word.
* Correct choice: most furnished

Final Answer:
- angriest
- laziest
- most serious
- saddest
- most comfortable
- most wonderful
- most frequent
- most talented
- crunchiest
- stablest (or *most stable*, depending on strictness, but *stablest* fits the suffix rule)
- most furnished
