Types of Exercises

1. Word Formation – These exercises involve transforming nouns into adjectives by adding the suffix “-ous.” Students learn the rule of adding “-ous” to nouns (e.g., “hazard” becomes “hazardous”) and practice applying this rule to various nouns. This enhances their vocabulary and understanding of how words are formed.

2. Fill-in-the-Blanks – Students complete sentences with the appropriate “-ous” adjective. This exercise helps students understand how these adjectives fit into sentence structures and how they modify nouns, thereby improving their sentence construction skills.

3. Matching Exercises – In these activities, students match nouns with their corresponding “-ous” adjectives (e.g., “danger” with “dangerous”). This reinforces the relationship between nouns and adjectives and enhances vocabulary retention.

4. Sentence Writing – Students use “-ous” adjectives in their own sentences, encouraging them to apply their understanding in a creative context. This not only reinforces their grasp of the “-ous” suffix but also improves their overall writing skills.

5. Identifying “-ous” Adjectives in Texts – Exercises might include passages where students need to identify all the “-ous” adjectives. This improves reading comprehension and analytical skills, as students learn to recognize and interpret the usage of “-ous” adjectives within a broader text.

6. Comparative and Superlative Forms – Students learn to form comparative and superlative adjectives from “-ous” adjectives (e.g., “dangerous,” “more dangerous,” “most dangerous”). Understanding how to express varying degrees of quality enhances their ability to describe and compare.

7. Prefix and Suffix Combination – Some worksheets may introduce students to the idea of adding prefixes to the “-ous” suffix, further expanding their vocabulary and understanding of word formation. For example, adding “in-” to “famous” to form “infamous.”

8. Error Correction – These exercises involve correcting mistakes in the use of “-ous” adjectives within sentences. This sharpens students’ editing skills and reinforces correct usage.

Using the -ous Suffix

The suffix “-ous” is used to form adjectives from nouns or other adjectives. It typically means “full of” or “having the quality of.” Here are three examples:

“Dangerous” – This word means full of danger. For instance, if something is “dangerous,” it poses a risk or hazard.

“Courageous” – This word means having courage or bravery. If someone is described as “courageous,” it means they have the quality of being brave, facing challenges without fear.

“Mysterious” – This word means full of mystery or something that is hard to understand or explain. For example, a hidden treasure might be described as “mysterious” because it’s difficult to find or comprehend.

Spelling With the Suffix -ous

It usually carries the meaning of “full of” or “having the quality of.” When adding the suffix “-ous” to a word, there are several spelling rules to consider:

Drop the final “e” – When the base word ends with an “e,” it’s usually dropped before adding “-ous.” For example:

Fame —> Famous
Sense —> Sensuous
Value —> Valorous

Keep the final “e” – Sometimes, if the final “e” is preceded by a consonant that’s pronounced, it’s retained before adding “-ous.” For example:

Brave —> Braveous (However, this spelling is uncommon; “Brave” typically becomes “Bravo” when combined with “-ous.”)

Words ending in “-ge” or “-dge” – When the base word ends with “-ge” or “-dge,” the “-ous” suffix is simply added without any alterations. For example:

Courage —> Courageous
Lodge —> Lodgeous (However, this spelling is not standard; typically, “Lodge” does not form an adjective with “-ous.”)

Words ending in “-y” – If the base word ends in “-y,” it’s replaced with “-i” before adding “-ous.” For example:

Fury —> Furious
Envy —> Envious

Words ending in “-ce” or “-cy” – If the base word ends in “-ce” or “-cy,” the “-ous” suffix is added directly. For example:

Grace —> Gracious
Democracy —> Democratic

Words ending in “-ious” – Some words already end in “-ious,” which means they already have the “-ious” suffix. When forming adjectives with “-ous,” the “-ious” suffix is usually replaced with “-ous.” For example:

Ambitious —> Ambitious (The base word “Ambition” is already an adjective ending in “-ious,” so no changes are needed.)

Delicious —> Delicous (The base word “Delicious” ends in “-ious,” so “-ious” is replaced with “-ous.”)

Irregularities – There are some exceptions and irregular spellings when adding “-ous.” For example:

Marvel —> Marvellous (In British English, “Marvelous” is spelled “Marvellous” with an extra “l” before “-ous.”)

Glamour —> Glamorous (The base word “Glamour” has an irregular spelling when forming the adjective “Glamorous.”)
