Clear guide to forming English adverbs: rules for turning adjectives, common suffixes (-ly), exceptions, and practical examples for everyday use.

Adverbs describe how, when, where, or to what extent something happens. This guide shows the main ways English adverbs form from adjectives and other words, so you can spot and create adverbs naturally.

Basic Formation

Most adverbs that describe manner form by adding -ly to an adjective. This turns a descriptive word into one that modifies a verb, an adjective, or another adverb.

Adjectives to Adverbs

When you add -ly, the adverb usually keeps the basic meaning of the adjective but applies it to an action or quality of manner.

Adjectives Ending in -y

If an adjective ends in -y, change the y to i before adding -ly so the form sounds natural and follows common spelling patterns.

She finished the puzzle(easy) than I expected.

Adverbs Without -ly

Some common adverbs do not end in -ly and often come from adjectives that have the same form as the adverb. These adverbs typically modify manner, time, place, or frequency and are important to learn because they resist the usual pattern.

Little vs. Seldom

Adverbs like little and seldom describe amount or frequency without using -ly. Little can function as an adverb when talking about extent, while seldom shows that something happens infrequently.

He(seldom) visits the museum on weekends.

He seldom visits the museum on weekends.

He ___ (seldom) visits the museum on weekends.

Adverbs of Time and Place

Adverbs that tell when or where something happens usually do not end in -ly and often come straight from nouns or remain in their short form. These adverbs help situate an action rather than describe how it happens.

After the intersection, walk(straight) to reach the library.

After the intersection, walk straight to reach the library.

After the intersection, walk ___ (straight) to reach the library.

Adverbs of Frequency

Adverbs of frequency show how often an action occurs and usually come before the main verb or after be. They do not take -ly and include words like always, often, and never.

I(often) check the news in the morning.

I often check the news in the morning.

I ___ (often) check the news in the morning.

Summary

Adverbs that describe manner usually form with -ly added to adjectives, but many common adverbs of time, place, and frequency do not use -ly and must be learned as fixed forms. Adverbs without -ly often come from adjectives, nouns, or short words that directly modify when, where, or how often an action happens.
