Types of Exercises

1. Matching Adjectives to Adverbs – This exercise requires students to match adjectives with their corresponding adverbs ending in “-ly.” It helps students recognize how adding “-ly” to an adjective transforms it into an adverb. For example, “quick” becomes “quickly.”

2. Sentence Completion – In these exercises, students fill in the blanks in sentences with the appropriate “-ly” adverb. This practice helps them understand how adverbs modify verbs, adjectives, or other adverbs within a sentence, enhancing their sentence construction skills. Passages or short stories rich in adverbs ending in “-ly” are included for students to identify and analyze the use of adverbs. This enhances reading comprehension and analytical skills.

3. Conversion Practice – Students convert adjectives into adverbs by adding “-ly” and use them in their own sentences. This not only reinforces the rule of transforming adjectives into adverbs but also encourages creative sentence formation. Students might be asked to write short paragraphs or stories using a list of adverbs ending in “-ly.” This exercise encourages creative expression while practicing the grammatical concept.

4. Error Correction – Worksheets may contain sentences with incorrect use of the “-ly” suffix. Students must identify and correct these mistakes, which sharpens their editing and proofreading skills.

5. Comparative and Superlative Adverbs – Some exercises focus on teaching students to form comparative and superlative forms of adverbs (e.g., “quickly” to “more quickly” to “most quickly”). This helps students learn to express degrees of comparison in actions.

Using the Suffix -ly

The suffix “-ly” is primarily used to form adverbs from adjectives, indicating manner, degree, or quality in relation to a verb, adjective, or another adverb. It’s added to the end of an adjective to modify it into an adverb, such as “quick” becoming “quickly” or “happy” becoming “happily.” However, not all adverbs end in “-ly,” so it’s essential to understand the specific rules and exceptions governing their usage in English grammar.

Formation of Adverbs – The suffix “-ly” is added to adjectives to form adverbs, primarily indicating manner, degree, or quality in relation to a verb, adjective, or another adverb. For example:

Spelling Considerations

Single Syllable Adjectives – When adding “-ly” to a single-syllable adjective, you typically just add the suffix without any spelling changes:

Adjective – slow
Adverb – slowly

Adjectives Ending in “y” – If the adjective ends in “y,” typically preceded by a consonant, the “y” is replaced with “i” before adding “-ly”:

Adjective – happy
Adverb – happily

Adjectives Ending in “le” – Adjectives ending in “le” usually drop the “e” before adding “-ly”:

Adjective – gentle
Adverb – gently

Adjectives Ending in “ic” – Adjectives ending in “ic” usually just add “-ally” to form the adverb:

Adjective – basic
Adverb – basically


Some adjectives have irregular forms when “-ly” is added:

Adjective – true
Adverb – truly

Some adjectives and adverbs don’t follow the pattern of adding “-ly” at all, like “fast” and “well.”

Some adverbs don’t end in “-ly” at all, such as “very,” “soon,” “now,” and “too.”


In some cases, when “-ly” is added to an adjective that precedes a noun, a hyphen might be used to avoid ambiguity:

A friendly-looking dog

An awfully written book

Word Stress

In most cases, the stress in the adverb falls on the syllable immediately preceding “-ly”:

Quick –> QUICK-ly
Happy –> HAP-pi-ly
