Adverbs of frequency are the measured drops in your grammar potion—place them carefully to control how often the magic happens.

Adverbs modify verbs, adverbs, adjectives, prepositions, prepositional phrases, conjunctions, and even entire clauses. In doing so, they change how we understand the meaning of the word or phrase they modify.

Independent adverbs do not modify a specific word or phrase in the sentence.

Adverbs of Frequency

Adverbs of frequency tell the listener or reader how often something happens. There are two subcategories of adverbs of frequency:

1. Definite frequency states a specific or exact time or schedule:

• daily, hourly, weekly, monthly, yearly, biweekly, quarterly

2. Indefinite frequency does not include a specific or exact time, but shows how often something happens:

• 100% → always
• 90% → usually
• 75% → often / frequently
• 50% → sometimes / occasionally
• 10% → seldom / rarely
• 0% → never

Simple Present Tense and Frequency

We use the simple present tense to talk about habits and routines. Adverbs of frequency are commonly used with this tense to show how regular an action is.

Adverbs of frequency most often modify verbs and sometimes adjectives.

Basic Sentence Structures (Review)

• Noun phrase NP (subject) + VP → Verb (intransitive verb)
• Noun phrase NP (subject) + VP → Verb (transitive verb) + NP (direct object)

Remember: the direct object is part of the verb phrase.

Indefinite Adverbs of Frequency: Modifying Verbs

1. Standard Placement

• Place the indefinite frequency adverb in front of the main verb.
• I often drive a car.

Structure: VP → (Auxiliary Verbs) + (Adverb) + Verb + (Verb Complements)

Note: Elements in parentheses are optional. So far, the only verb complement introduced is the direct object.

Note: If your sentence includes an auxiliary verb or modal verb, such as can, must, or should, the adverb of frequency goes between the auxiliary/modal and the main verb. Auxiliary verbs and modals will be taught in later lessons.

2. Introductory Position (for Emphasis)

• These adverbs may begin a sentence and are usually followed by a comma: usually, sometimes, normally, occasionally, often, and frequently.
• Sometimes, it snows in March.

Structure: (Adverb), NP subject + VP → (Auxiliary Verbs) + Verb + (Verb Complements)

3. “Each” and “Every”

• Frequency phrases that begin with “each” and “every” are placed at the beginning or the end of a sentence:
• Every year, we celebrate Christmas.
• We celebrate Christmas every year.

Structure: (Adverb), NP subject + VP → (Auxiliary Verb) + Verb + (Verb Complements)

Structure: NP subject + VP → (Auxiliary Verb) + Verb + (Verb Complements) + (Adverb)

4. Emphatic/Inversion Structures

• Seldom, rarely, hardly ever, and never can appear at the beginning of the sentence for emphasis. This causes subject-auxiliary inversion:
• Never have I stolen a cookie!

Note: When these adverbs appear at the end of a sentence, they do not cause inversion.

• I have never stolen a cookie.

Note: Don’t worry about this concept yet. It is here as a preview for your notes.  

5. “To Be” Verb Placement

• When the main verb is a form of “to be,” the adverb usually comes after the verb:
• You are usually kind.
• The sky is often cloudy.

Structure: NP subject + VP → Verb “to be” + (Adverb) + Verb Complement

Note: When using a “to be” verb, a verb complement is required in these sentence patterns: predicate adjective, predicate nominative, or adverbial complement. That is why it is not placed in parentheses. 

Indefinite Adverbs of Frequency: Modifying Adjectives  

1. “To Be” Verb with a Predicate Adjective

• Place the adverb after the verb “to be”:
• She is always pretty. In this sentence, “always” is placed after “is” and tells how often “she is pretty” is true.

Structure: NP subject + VP → Verb “to be” + (Adverb) + Verb Complement

2. Emphasis (Less Common/Formal)

• The adverb can appear before “to be” in more formal or literary structures:
• I never was there.

Structure: NP subject + VP → (Adverb) + Verb “to be” + Verb Complement

Definite Adverbs of Frequency and Adverbial Phrases:Modifying Verbs

1. –ly Definite Frequency Adverbs

• Many definite frequency adverbs ending in “-ly” are most natural at the end of a sentence, but may shift depending on emphasis and sentence complexity:
• I jog daily.
• She visits weekly.

Note: Frequency phrases, such as every day, each week, and once a month, can also appear at the end of a sentence.

• I jog every day.
• We meet once a month.

Structure: NP subject + VP → (Auxiliary Verb) + Verb + (Verb Complements) + (Adverb)

2. Introductory Position

• Adverbs may appear at the beginning of a sentence for emphasis:
• Every day, I jog.

Structure: (Adverb), NP subject + VP → (Auxiliary Verb) + Verb + (Verb Complements)

Important Note

When an adverb appears before the subject in introductory position, it still modifies the verb, not the subject.

Adverb Interaction (Preview)

When multiple adverbial phrases are present, such as prepositional, infinitive, or participle phrases, placement may shift for clarity and emphasis.
