Adverbs — Basic English Grammar
Adverbs modify verbs, adjectives, and other adverbs. This guide covers everything you need to know — what adverbs are, how to form them, the 5 types, their position in a sentence, and common mistakes to avoid.
What Is an Adverb?
An adverb is a word that modifies a verb, an adjective, or another adverb. Adverbs give us more information about how, when, where, how often, or to what degree something happens.
Adverbs answer one of these questions: How? When? Where? How often? To what degree? If a word answers one of these about a verb, adjective, or adverb — it is an adverb.
The 5 Types of Adverbs
Adverbs can be grouped into five main categories based on what question they answer:
Adverbs of Manner
Describe how an action is performed.
Adverbs of Time
Describe when an action happens.
Adverbs of Place
Describe where an action happens.
Adverbs of Frequency
Describe how often an action happens.
Adverbs of Degree
Describe to what extent something is true.
How to Form Adverbs from Adjectives
Most adverbs in English are formed by adding a suffix to an adjective. Here are the key rules:
Public does NOT become publically — it becomes publicly. This is the most common exception students get wrong. Always remember: public → publicly.
The Special Case of Good and Well
One of the most common mistakes in English is confusing good (adjective) with well (adverb).
Ask yourself: is the word describing a noun or a verb/adjective/adverb? If it describes a noun → use good (adjective). If it describes how something is done → use well (adverb).
Position of Adverbs in a Sentence
Where you place an adverb in a sentence matters. The rules differ depending on the type of adverb:
Adverbs of Manner
Usually placed after the verb or after the object if there is one.
Adverbs of Frequency
Placed before the main verb, but after the verb to be.
Adverbs of Time and Place
Usually placed at the beginning or end of the sentence.
Comparison of Adverbs
Like adjectives, adverbs have three degrees of comparison — positive, comparative, and superlative.
One-syllable adverbs usually add –er / –est. Adverbs ending in –ly use more / most. Irregular adverbs like well and badly change form completely.
Common Mistakes with Adverbs
Lately means recently — it does not mean “late.”
“I haven’t been sleeping well lately.” = recently. “She arrived late.” = not on time.
