What Are Adverbs of Frequency?
Every day, we talk about our routines, habits, and how often things happen in our lives. When someone asks you "How often do you exercise?" or "Do you ever eat fast food?", you need special words to answer these questions accurately. These special words are called adverbs of frequency, and they tell us how often an action happens — from things we do all the time to things we never do at all.
Adverbs of frequency range from 0% (never) to 100% (always). They are one of the most essential grammar topics in English because they appear in almost every conversation about daily life, habits, routines, and schedules. They are especially important when used with the Simple Present Tense, which is the main tense for describing regular actions and habits.
In this article, we will explore every adverb of frequency on the scale, learn exactly where to place them in a sentence, discover the difference between single-word adverbs and longer frequency expressions, and master the most common mistakes that learners make.
Adverbs of frequency are among the first grammar topics taught in English because they are used in every single conversation about routines and habits. Without them, you cannot answer the question "How often...?" properly. Mastering their position in a sentence is the key to sounding natural.
The Frequency Scale
The frequency scale shows all adverbs of frequency arranged from 100% (something that happens every single time) down to 0% (something that never happens). Each adverb represents a different level of frequency. Study this table carefully — it is the foundation of everything that follows.
| % | Adverb | Example Sentence |
|---|---|---|
| 100% | always | I always brush my teeth before bed. |
| 90% | usually | She usually walks to school. |
| 85% | normally | We normally have dinner at seven. |
| 80% | frequently | He frequently visits his grandparents. |
| 70% | often | They often play football after school. |
| 50% | sometimes | I sometimes eat pizza for lunch. |
| 30% | occasionally | We occasionally go to the cinema. |
| 10% | rarely | She rarely eats chocolate. |
| 10% | seldom | He seldom watches television. |
| 5% | hardly ever | They hardly ever go on holiday. |
| 0% | never | I never drink coffee. |
Seldom and rarely have the same meaning (approximately 10%), but seldom is more formal and literary. In everyday conversation, native speakers prefer rarely. You will see seldom more often in written English, exams, and news articles.
Remember that never and hardly ever already have a negative meaning. Do not use them with "not" or "don't" — this creates a double negative, which is incorrect in standard English:
✘ I don't never eat meat.
✔ I never eat meat.
Position in Sentences — With Regular Verbs
The most important rule about adverbs of frequency is knowing where to put them in a sentence. With regular verbs (all verbs except "be"), the adverb of frequency goes before the main verb. This is different from many other languages, so pay special attention to this rule.
Subject + adverb of frequency + main verb + ...
The adverb of frequency is placed between the subject and the main verb. Think of it as the adverb sitting right in front of the verb, telling you how often the action happens.
| Subject | Adverb | Verb | Full Sentence |
|---|---|---|---|
| I | always | wake up | I always wake up at 7 o'clock. |
| She | usually | drinks | She usually drinks tea in the morning. |
| We | often | go | We often go to the park on Sundays. |
| They | sometimes | watch | They sometimes watch films together. |
| He | rarely | eats | He rarely eats fast food. |
| My parents | never | argue | My parents never argue about money. |
Sometimes and occasionally are more flexible than other frequency adverbs. They can also appear at the beginning or end of a sentence:
Sometimes I go jogging. (beginning)
I go jogging sometimes. (end)
I sometimes go jogging. (middle — standard position)
All three are correct, but the middle position is the most common.
Position in Sentences — With “Be”
Here is where many learners make mistakes. When the main verb is "be" (am, is, are, was, were), the adverb of frequency goes after the verb "be" — not before it. This is the opposite of the regular verb rule.
Subject + be (am/is/are) + adverb of frequency + ...
With the verb "be", the adverb comes after the verb. The reason is that "be" is a special verb in English — it behaves differently from all other verbs.
| Subject | Be | Adverb | Full Sentence |
|---|---|---|---|
| I | am | always | I am always happy to see you. |
| She | is | usually | She is usually on time for class. |
| They | are | often | They are often tired after work. |
| He | is | sometimes | He is sometimes late for meetings. |
| The bus | is | rarely | The bus is rarely on time. |
| It | is | never | It is never too late to learn. |
Do not place the adverb before the verb "be". This is wrong:
✘ She always is late for class.
✔ She is always late for class.
✘ They usually are hungry after school.
✔ They are usually hungry after school.
Remember: Regular verbs → adverb BEFORE the verb. Verb "be" → adverb AFTER the verb.
Position with Auxiliary & Modal Verbs
When a sentence has an auxiliary verb (have, has, do, does, did, will) or a modal verb (can, could, should, would, may, might, must), the adverb of frequency goes between the auxiliary/modal and the main verb. This rule applies to all tenses that use helping verbs.
Subject + auxiliary/modal + adverb of frequency + main verb + ...
The adverb sits between the helper and the main action word. Think of it as a sandwich: the auxiliary is the bread on the left, the main verb is the bread on the right, and the adverb is the filling in the middle.
| Auxiliary/Modal | Example Sentence |
|---|---|
| have | I have never been to Japan. |
| has | She has always wanted to be a doctor. |
| can | He can usually finish his homework before dinner. |
| will | They will probably arrive late. |
| should | You should always check your answers twice. |
| must | Students must never cheat on exams. |
| would | She would often read stories to her children. |
The structure would + often is used to talk about repeated actions in the past, similar to "used to". For example: "When I was a child, I would often play in the garden." This is a slightly more formal and literary way to describe past habits.
Frequency Expressions
In addition to single-word adverbs (always, never, etc.), English has frequency expressions — longer phrases that tell us exactly how often something happens. The most important difference is their position: while single-word adverbs go in the middle of the sentence, frequency expressions usually go at the end of the sentence.
Subject + verb + object + frequency expression
Frequency expressions go at the end of the sentence, after the verb and object. They can also appear at the beginning for emphasis, but the end position is standard.
| Expression | Example Sentence |
|---|---|
| every day | I drink water every day. |
| every morning | She goes for a run every morning. |
| once a week | We have a team meeting once a week. |
| twice a month | He visits his parents twice a month. |
| three times a year | They go on holiday three times a year. |
| every other day | I wash my hair every other day. |
| on Mondays | We have English class on Mondays. |
| at weekends | They play tennis at weekends. |
| once in a while | I eat ice cream once in a while. |
Do not confuse the position of single-word adverbs with frequency expressions:
✔ I always drink coffee. (single word → before the verb)
✔ I drink coffee every day. (expression → end of sentence)
✘ I every day drink coffee.
✘ I drink always coffee.
Single-word adverbs = middle position. Expressions = end position.
The rhythm of your life is written in adverbs of frequency. Always, sometimes, never — these small words paint the big picture of who you are and what you do.

Questions with Frequency Adverbs
To ask about frequency in English, we use special question words and structures. The most common question is "How often...?", but we also use "Do you ever...?" and "Have you ever...?" to ask about experiences and habits. Understanding these question forms is essential for natural conversation.
How often + do/does + subject + verb ...?
Do/Does + subject + ever + verb ...?
Have/Has + subject + ever + past participle ...?
| Question | Answer |
|---|---|
| How often do you exercise? | I usually exercise three times a week. |
| How often does she visit her grandmother? | She visits her grandmother once a month. |
| Do you ever eat sushi? | Yes, I sometimes eat sushi. |
| Does he ever cook dinner? | No, he never cooks dinner. |
| Have you ever been to London? | No, I have never been to London. |
| How often do they go on holiday? | They rarely go on holiday — maybe once a year. |
Use ever in questions to mean "at any time":
"Do you ever drink coffee?"
Use never in negative answers:
"No, I never drink coffee."
Do not use "never" in questions. ✘ "Do you never drink coffee?" sounds unnatural. Use "ever" instead: ✔ "Do you ever drink coffee?"
Common Mistakes
Even advanced learners make mistakes with adverbs of frequency. The three most common errors are: wrong position with "be", wrong position with auxiliaries, and double negatives. Let us look at each one and learn how to avoid them.
The adverb must come after the verb "be", not before it:
✘ He always is tired after work.
✔ He is always tired after work.
✘ They usually are late for class.
✔ They are usually late for class.
The adverb goes between the auxiliary and the main verb:
✘ She has finished always her homework on time.
✔ She has always finished her homework on time.
✘ I can find usually a parking space.
✔ I can usually find a parking space.
Never and hardly ever are already negative. Do not combine them with "not" or "don't":
✘ I don't never eat fish.
✔ I never eat fish.
✘ She doesn't hardly ever go out.
✔ She hardly ever goes out.
Frequency expressions (every day, once a week, etc.) go at the end, not in the middle:
✘ She every day walks to school.
✔ She walks to school every day.
✘ I twice a week go swimming.
✔ I go swimming twice a week.
There is one special use of always: when combined with the Present Continuous Tense, it expresses annoyance or complaint about something that happens too frequently:
"He is always losing his keys!" (I am annoyed by this.)
"She is always talking in class!" (The teacher is complaining.)
This is not a regular use of frequency — it shows the speaker's emotion.
Adverbs of Frequency vs. Frequency Expressions
Now that we have studied both types, let us compare them side by side. Understanding the differences between single-word adverbs and longer frequency expressions will help you use them correctly and make your English more precise and natural.
| Feature | Adverbs of Frequency | Frequency Expressions |
|---|---|---|
| Form | Single word | Phrase (two or more words) |
| Examples | always, usually, often, never | every day, once a week, on Mondays |
| Position | Before main verb / after "be" | End of sentence (usually) |
| Flexibility | Fixed position (except sometimes) | Can go at beginning or end |
| Precision | General (approximate %) | Specific (exact number of times) |
| Use | General habits and routines | Exact schedules and frequencies |
You can combine a single-word adverb with a frequency expression in the same sentence for extra clarity:
"I usually exercise three times a week."
"She always has a coffee break every morning."
The adverb gives the general impression, and the expression gives the specific detail.
Never put a frequency expression in the middle position (where single-word adverbs go), and never put a single-word adverb at the end (where expressions go):
✘ I every day wake up early. → ✔ I wake up early every day.
✘ I wake up early always. → ✔ I always wake up early.
Keep each type in its correct position for natural-sounding English.
