Adverbs of Frequency: Rules, Position and Examples

Overview

An adverb of frequency is an adverb that tells how often an action occurs. It answers the question how often or how many times. When someone says they always check their email in the morning, rarely miss a deadline, or meet with a client twice a week, each expression is an adverb of frequency describing the regularity of that action.

English divides adverbs of frequency into two groups. Indefinite adverbs of frequency give a general sense of how often something happens without naming a specific number: always, usually, often, sometimes, rarely, never. Definite adverbs of frequency state a precise count or named interval: once, twice, daily, every Monday, three times a month. The two groups behave differently in terms of where they are placed in a sentence.

Indefinite Adverbs of Frequency

Indefinite adverbs of frequency express how often something happens in relative rather than exact terms. They are arranged along a scale from always at the top to never at the bottom.

Position of Indefinite Adverbs of Frequency

Before the main verb: In a sentence with a single main verb (not an auxiliary), the indefinite adverb of frequency goes directly before that verb.

After the verb to be: When the main verb is be, the adverb of frequency follows it. This is the one case where the adverb comes after, rather than before, the verb.

After the first auxiliary verb: In sentences with one or more auxiliary verbs, the indefinite adverb of frequency is placed after the first auxiliary, before the main verb.

Position at the Beginning or End for Emphasis

Some indefinite adverbs, particularly sometimes, usually, often, and occasionally, can be placed at the beginning or end of a sentence for emphasis or rhythm. Always and never are not typically moved to the end position in standard usage.

The stronger adverbs at the extremes (always, never, rarely) are more fixed in their mid-sentence position.

Definite Adverbs of Frequency

Definite adverbs of frequency state a specific count or named time interval. They include expressions such as once, twice, three times, daily, weekly, monthly, annually, every day, every other week, and twice a month.

Definite adverbs of frequency typically appear at the end of the sentence or clause, or at the beginning when they are being emphasised or set as the topic.

Definite adverbs of frequency do not slot into the mid-sentence position used by indefinite adverbs.

Single-word adverbs such as daily, weekly, and monthly can also appear before a noun in an attributive role, but that use is adjectival rather than adverbial.

Adverbs of Frequency in Questions and Negatives

In questions, the position rules for indefinite adverbs of frequency remain the same: the adverb sits after the first auxiliary verb, which is now moved to the front of the sentence to form the question.

In negative sentences with auxiliary verbs, the adverb of frequency follows the first auxiliary, placing it before the negative particle not or its contracted form.

Never itself makes a sentence negative in meaning. It should not be combined with not in the same clause, as doing so creates a double negative.

Common Mistakes to Avoid

Mistake 1: Placing an Indefinite Adverb of Frequency After the Main Verb

Indefinite adverbs of frequency belong before the main verb, not after it.

Mistake 2: Placing the Adverb Before Be Instead of After

The verb be is the one case where the adverb of frequency follows, rather than precedes, the verb.

Mistake 3: Placing a Definite Adverb of Frequency in the Mid-Sentence Position

Definite adverbs of frequency go at the end of the clause, not in the mid-sentence slot used by indefinite adverbs.

Mistake 4: Using a Double Negative With Never

Never already carries a negative meaning. Adding not or don't in the same clause creates a double negative, which is non-standard in formal English.

Mistake 5: Placing the Adverb Between the Auxiliary and Be

In sentences where be follows an auxiliary verb, the adverb of frequency comes after the first auxiliary, before be. Placing it after be in this structure produces the wrong word order.

Mistake 6: Confusing Ever With Always in Questions

Ever is used in questions and negatives to ask about or deny any occurrence at all. Always is used for habitual, unbroken frequency. Substituting one for the other shifts the meaning of the question.

Practice Exercises

Exercise 1: Place the Adverb Correctly

Rewrite each sentence, inserting the adverb in brackets in the correct position.

3. He has attended a training session outside of his home country. (never)
4. They review the figures with the finance team. (twice a month)
5. The system has been updated before the scheduled maintenance window. (occasionally)
6. She arrives late because she takes the first available train. (rarely)

Exercise 2: Choose the Correct Position

Choose the sentence in each pair that has the correct word order.

1. a) She always is the first to arrive at the morning briefing session. b) She is always the first to arrive at the morning briefing session.
2. a) He rarely checks his messages after eight in the evening. b) He checks rarely his messages after eight in the evening.
3. a) The board meets quarterly to review the strategic direction of the company. b) The board quarterly meets to review the strategic direction of the company.
4. a) They have always been committed to meeting every agreed deadline without exception. b) They always have been committed to meeting every agreed deadline without exception.

Exercise 3: Correct the Error

Each sentence contains one adverb of frequency error. Rewrite it correctly.

1. The committee doesn't never approve a budget without a full review of the figures.
2. She is submitting usually her completed work two days before the stated deadline.
3. He every day attends the briefing that is held at nine o'clock in the main room.
4. They have been always willing to support new initiatives proposed by the team.
5. She always is the most prepared person in the room when a presentation takes place.
6. The manager has not never received a complaint about this member of the team.

Exercise 4: Definite or Indefinite?

Label each adverb of frequency as definite (D) or indefinite (I), then write a sentence of your own using it correctly.

1. twice a week
2. rarely
3. monthly
4. sometimes
5. every other day
6. frequently

Summary

Indefinite adverbs belong before the main verb, after be, or after the first auxiliary. Definite adverbs belong at the end of the clause.
