What Is an Adverb?

Adverb definition from Merriam-Webster

• According to Merriam-Webster Dictionary (the leading US dictionary), an adverb is “a word that modifies a verb, an adjective, or another adverb.”
• Examples from Merriam-Webster: “arrived early”, “runs slowly”, “stayed home”, “works hard”.

Adverb definition from BBC Bitesize

• BBC Bitesize (UK educational resource) defines an adverb as “a word that describes a verb, an adjective, or another adverb.”
• Adverbs can tell us how, where, when, or how often something happens.

Adverb definition from Grammarly

• Grammarly (popular grammar blog) explains that adverbs modify verbs, adjectives, other adverbs, or even whole sentences.
• Grammarly emphasizes that adverbs can appear anywhere in a sentence.

What this means: The core definition is consistent across all major sources—adverbs are modifiers that add detail to actions, descriptions, or other modifiers.

What Is an Example of an Adverb?

Example of an adverb modifying a verb

• “He ran quickly” — quickly modifies the verb ran (Merriam-Webster).
• “She speaks English well” — well modifies the verb speaks (British Council).

Example of an adverb modifying an adjective

• “She is very tall” — very modifies the adjective tall (Grammarly).
• “The movie was extremely boring” — extremely modifies boring.

Example of an adverb modifying another adverb

• “He drives quite fast” — quite modifies the adverb fast (Grammarly).
• “She almost always arrives on time” — almost modifies always.

The pattern: Adverbs can stack—one adverb can modify another to create precise shades of meaning.

How to Explain Adverbs to a Child?

Simple adverb explanation for kids

• The British Council (global English teaching organization) teaches that adverbs describe how somebody does something.
• Examples: “I speak English well”, “He plays hockey badly”, “We try to do our homework correctly”.
• BBC Bitesize (UK educational resource) suggests using everyday actions: “eat slowly”, “sing loudly”.

Adverb examples for children

• Use actions: “The child ran happily towards their mother” (Twinkl (educational resource)).
• Compare: “James clapped loudly” vs “James clapped” — the adverb adds detail.

Why this matters: For kids, adverbs are best taught through actions they already know—running, eating, singing—so the concept feels concrete, not abstract.

How Do I Identify an Adverb?

Check if it answers how, when, where

• Adverbs often answer the questions: how? (quickly), when? (now), where? (here), how often? (always) (BBC Bitesize).

Look for -ly suffix

• Many adverbs end in -ly, but not all. Examples: “quickly”, “slowly”, “happily” (British Council).
• Exceptions: “fast”, “hard”, “well”, “very” do not end in -ly.

Identify adverb vs adjective

• Adjectives describe nouns; adverbs describe verbs, adjectives, or other adverbs (K5 Learning (educational site)).
• Example: “She is a happy girl” (happy modifies girl) vs “She smiled happily” (happily modifies smiled).

The trade-off: Relying on the -ly rule catches most adverbs but misses common ones like ‘very’ and ‘fast’. Teach the question test instead.
