## Introduction
Adverbs modify verbs, adjectives, or other adverbs. They often tell us **how**, **when**, **where**, or **to what degree** something happens. This unit focuses on adverbs that describe *how* actions happen (manner adverbs) — for example: quickly, badly, suddenly.
> Definition: An adverb is a word that modifies a verb, an adjective, or another adverb and often answers the questions how, when, where, or to what extent.
## 1. Forming adverbs from adjectives
Most manner adverbs in English are formed by adding **-ly** to an adjective.
### Rules and examples
- Base rule: adjective + **-ly** → adverb
- quick → quickly
- careful → carefully
- sudden → suddenly
- Spelling changes for some adjectives:
- easy → easily (drop -y, add -ily)
- heavy → heavily (change -y to -i + -ly)
> Tip: Not every adjective forms an adverb with -ly (see irregulars and exceptions below).
### Table: adjective → adverb
| Adjective | Adverb |
|---|---|
| quick | quickly |
| bad | badly |
| sudden | suddenly |
| careful | carefully |
| heavy | heavily |
## 2. What adverbs describe
Adverbs of manner tell you how something happens or how someone does something.
- Examples:
- The train stopped **suddenly**.
- I opened the door **slowly**.
- Please listen **carefully**.
- I understand you **perfectly**.
- It’s raining **heavily**.
> Definition: A manner adverb describes the way in which an action is performed.
## 3. Adjectives vs Adverbs — comparison and usage
Some words exist as both adjectives and adverbs without changing form (context tells you which): **hard, fast, late, early**.
- As adjectives:
- Sue’s job is very **hard**.
- Ben is a **fast** runner.
- The bus was **late** / **early**.
- As adverbs:
- Sue works very **hard**. (not *hardly*)
- Ben can run **fast**.
- I went to bed **late** / **early**.
Special case: **good** (adjective) → **well** (adverb)
- Your English is very **good**. (adjective)
- You speak English very **well**. (adverb)
- Note: **well** can also be an adjective meaning healthy: “I’m very **well**.”
### Table: common confusions
| Meaning | Adjective | Adverb |
|---|---:|---:|
| Quality (adj) | good | — |
| Manner (adv) | — | well |
| Fast/Hard (both) | fast / hard | fast / hard |
## 4. Placement of adverbs (manner)
- Manner adverbs typically come: after the main verb or after the object.
- He speaks **quietly**. / She painted the wall **carefully**.
- With auxiliary verbs or perfect tenses, the adverb can come after the auxiliary:
- She has **always** worked hard.
## 5. Common mistakes and how to avoid them
- Don’t use an adjective where an adverb is required:
- Incorrect: Sue speaks very **quiet**. → Correct: Sue speaks very **quietly**.
- Don’t change words that already function as adverbs:
- Incorrect: Sue works **very hardly**. (means almost never) → Correct: Sue works **very hard**.
- Remember the special pair: **good** → **well** for manner.
Fun fact: The adverb form with -ly comes from the Old English suffix -lic, which meant “like” or “in the manner of,” so modern -ly literally means “in the manner of.”
## 6. Practice with contextual examples
- He ate his dinner **very quickly**. (how he ate)
- **Suddenly** the shelf fell down. (how the event happened)
- Sue speaks **very quietly**. (manner of speaking)
- Our team played **badly** last week. (manner of playing)
- I waited **nervously** for the result.
