Educational worksheet for practicing prefixes and suffixes with a word-building activity.

Problem Overview:

The task is to fill in the prefixes and suffixes for a list of root words using the provided banks of prefixes and suffixes. The goal is to form meaningful words by combining the given root words with appropriate prefixes and suffixes.

Provided Banks:

- Prefixes: dis-, im-, mis-, un-, il-, in-, re-
- Suffixes: -able, -ance, -ion, -ment, -al, -ful, -ly, -y

Solution Approach:

1. Understand the Prefixes and Suffixes:
- Prefixes modify the meaning of a word (e.g., dis- means "not," un- means "opposite").
- Suffixes change the part of speech or add meaning (e.g., -able means "capable of," -ment means "state or condition").

2. Analyze Each Root Word:
- For each root word, determine which prefix and suffix can logically be added to form a valid word.
- Use common English vocabulary knowledge to identify possible combinations.

3. Form Words:
- Combine the root word with one or more prefixes and suffixes to create meaningful words.
- Ensure that the resulting words are grammatically correct and make sense.

Step-by-Step Solution:

#### Left Column: Prefix - Root Word - Suffix
1. place:
- Possible prefix: re- (meaning "again")
- Possible suffix: -ment (meaning "state or condition")
- Result: replacement

2. law:
- Possible prefix: un- (meaning "opposite")
- Possible suffix: -ful (meaning "full of")
- Result: unlawful

3. legal:
- Possible prefix: il- (meaning "not")
- Possible suffix: -ity (not in the bank, but commonly used)
- Since -ity is not in the bank, we can use -al instead.
- Result: illegal

4. mature:
- Possible prefix: dis- (meaning "not")
- Possible suffix: -ly (meaning "in the manner of")
- Result: dismally (Note: This might not fit perfectly, but it's a valid combination)

5. taken:
- Possible prefix: un- (meaning "opposite")
- Possible suffix: -able (meaning "capable of")
- Result: untaken (This is less common, but valid)

6. humane:
- Possible prefix: in- (meaning "not")
- Possible suffix: -ity (not in the bank, but commonly used)
- Since -ity is not in the bank, we can use -al instead.
- Result: inhumane

7. assign:
- Possible prefix: re- (meaning "again")
- Possible suffix: -ment (meaning "state or condition")
- Result: reassignment

8. health:
- Possible prefix: un- (meaning "opposite")
- Possible suffix: -y (meaning "characterized by")
- Result: unhealthy

9. account:
- Possible prefix: un- (meaning "opposite")
- Possible suffix: -able (meaning "capable of")
- Result: unaccountable

10. live:
- Possible prefix: un- (meaning "opposite")
- Possible suffix: -ly (meaning "in the manner of")
- Result: unlively

#### Right Column: Prefix - Root Word - Suffix
1. enforce:
- Possible prefix: dis- (meaning "not")
- Possible suffix: -ment (meaning "state or condition")
- Result: disenforcement

2. arrange:
- Possible prefix: mis- (meaning "wrongly")
- Possible suffix: -ment (meaning "state or condition")
- Result: misarrangement

3. develop:
- Possible prefix: un- (meaning "opposite")
- Possible suffix: -ment (meaning "state or condition")
- Result: underdevelopment

4. taste:
- Possible prefix: dis- (meaning "not")
- Possible suffix: -ful (meaning "full of")
- Result: distasteful

5. finite:
- Possible prefix: in- (meaning "not")
- Possible suffix: -ity (not in the bank, but commonly used)
- Since -ity is not in the bank, we can use -al instead.
- Result: infinite

6. act:
- Possible prefix: in- (meaning "not")
- Possible suffix: -ive (not in the bank, but commonly used)
- Since -ive is not in the bank, we can use -al instead.
- Result: inactive

7. help:
- Possible prefix: un- (meaning "opposite")
- Possible suffix: -ful (meaning "full of")
- Result: unhelpful

8. know:
- Possible prefix: un- (meaning "opposite")
- Possible suffix: -able (meaning "capable of")
- Result: unknowable

9. appear:
- Possible prefix: dis- (meaning "not")
- Possible suffix: -ance (meaning "state or condition")
- Result: disappearance

10. avoid:
- Possible prefix: un- (meaning "opposite")
- Possible suffix: -able (meaning "capable of")
- Result: unavoidable
