Grade 6 English worksheet on suffixes, featuring exercises to add "able" and "ness" to words like "peace," "love," "shy," and "dark" to create meaningful terms.

Of course! Let's solve this Grade 6 English suffix worksheet step by step.

## Part 1: Adding the suffix "able"

The suffix "-able" is added to verbs (and sometimes nouns) to form adjectives. It usually means "capable of being" or "fit to be."

For example:
- `love` + `able` = `lovable` → capable of being loved.
- `punish` + `able` = `punishable` → capable of being punished.

Let’s go through each word and see if adding “-able” creates a real, meaningful word.

Words from the list:

1. peace → *peaceable* ✔ (meaning: calm, not aggressive)
2. love → *lovable* ✔
3. punish → *punishable* ✔
4. suit → *suitable* ✔
5. piece → *pieceable* ✘ (Not a standard word; we say “reassemble” or “put together,” not “pieceable”)
6. notice → *noticeable* ✔
7. joke → *jokeable* ✘ (Not a word — we might say “joke-worthy,” but not “jokeable”)
8. bear → *bearable* ✔ (meaning: able to be endured)
9. debate → *debatable* ✔
10. laugh → *laughable* ✔
11. party → *partyable* ✘ (Not a standard word — we might say “festive” or “party-ready,” but not “partyable”)
12. bare → *bareable* ✘ (Not a word — we say “bearable” for endurance, not “bareable”)
13. pleasure → *pleasurable* ✔
14. cry → *cryable* ✘ (Not a word — we say “tear-jerking” or “sad,” but not “cryable”)
15. size → *sizeable* ✔ (meaning: large enough to be noticeable)

> 💡 Note: Sometimes words like “pieceable” or “partyable” might sound logical, but they are not standard English words. We only include those that are commonly used and found in dictionaries.

✔ Correct answers for "-able":

```
peaceable
lovable
punishable
suitable

bearable

laughable

sizeable
```

## Part 2: Adding the suffix "ness"

The suffix "-ness" is added to adjectives to form nouns. It means “the state or condition of being [adjective].”

For example:
- `shy` + `ness` = `shyness` → the state of being shy.
- `sad` + `ness` = `sadness` → the state of being sad.

Let’s check each word:

Words from the list:

1. shy → *shyness* ✔
2. dark → *darkness* ✔
3. sad → *sadness* ✔
4. weak → *weakness* ✔
5. light → *lightness* ✔ (can mean not heavy OR brightness — both valid)
6. greedy → *greediness* ✔
7. wilder → *wilderness* ✘ — Wait! “Wilder” is the comparative form of “wild.” We can add “-ness” to “wild” → `wildness`. But “wilder” + “ness” = “wilderness” — which is actually a real word, but it comes from “wild” + “erness,” not “wilder” + “ness.” So technically, “wilder” is not the base adjective. So we should use wild, not wilder.
- So: wild → *wildness* ✔
- wilder → *wilderness* — but this is misleading because “wilderness” doesn’t come from “wilder.”
- ✔ So we’ll accept wild → wildness, and reject “wilder” as a base for “-ness.”

8. good → *goodness* ✔
9. clean → *cleanness* ✔ (less common than “cleanliness,” but still correct)
10. wild → *wildness* ✔
11. bad → *badness* ✔
12. clever → *cleverness* ✔

> 💡 Note: “Clean” can also become “cleanliness,” but “cleanness” is also acceptable. For Grade 6, both may be accepted, but “cleanness” is the direct formation.

✔ Correct answers for "-ness":

```
shyness
darkness
sadness
weakness
lightness
greediness
wildness
goodness
cleanness
badness
cleverness
```

> 🚫 We exclude “wilder” because it’s not the base adjective — “wild” is.
