Analyze the first word equation

The worksheet provides definitions and examples to fill in the blank boxes.
For the first section, the example shows:

• \( \text{read} = \text{to comprehend a text} \)
• \( \text{re} = \text{to do again} \)
• \( \text{reread} = \text{to read a text over again} \)

Using Word Analysis, we identify:

• Prefix: \( \text{re} \)
• Base Word: \( \text{read} \)
• New Word: \( \text{reread} \)

Analyze the second word equation

For the second section, the example shows:

• \( \text{thank} = \text{to express appreciation} \)
• \( \text{ful} = \text{full of} \)
• \( \text{thankful} = \text{to be full of appreciation} \)

Using Word Analysis, we identify:

• Base Word: \( \text{thank} \)
• Suffix: \( \text{ful} \)
• New Word: \( \text{thankful} \)

Analyze the third word equation

For the third section, the example shows:

• \( \text{un} = \text{not} \)
• \( \text{love} = \text{care, devotion, strong feeling of like} \)
• \( \text{able} = \text{can do} \)
• \( \text{unlovable} = \text{not able to love, not lovable} \)

Using Word Analysis, we identify:

• Prefix: \( \text{un} \)
• Base Word: \( \text{love} \)
• Suffix: \( \text{able} \)
• New Word: \( \text{unlovable} \)
