The core difference between an adverb of time and an adverb of frequency lies in the specific question they answer about an action: an adverb of time indicates when an action occurs, while an adverb of frequency specifies how often an action takes place.
These two types of adverbs provide crucial details that enrich our understanding of events and activities described in sentences. While both modify verbs, adjectives, or other adverbs, their distinct functions guide their usage and typical placement within a sentence.
Understanding Adverbs of Time
Adverbs of time provide information about when an action happens, for how long, or until when. They answer the question "When?".
- Function: To pinpoint the specific moment, period, or duration of an action.
- Common Examples: now, yesterday, soon, later, today, tonight, tomorrow, early, recently, already, still, yet, last year, eventually.
- Typical Placement: Adverbs of time are highly flexible and can often be placed at the beginning or end of a sentence. Placing them at the beginning can add emphasis.
- Examples:
- "I will call you later." (End of sentence)
- "Yesterday, we visited the museum." (Beginning of sentence)
- "She has already finished her work." (Before the main verb)
- Examples:

Understanding Adverbs of Frequency
Adverbs of frequency give extra information on how often an action happens. They answer the question "How often?". This is the key distinction from adverbs of time, which focus on when it happens rather than its regularity.
- Function: To describe the regularity or repetition of an action.
- Common Examples: always, usually, often, sometimes, rarely, seldom, never, weekly, daily, annually, occasionally, hardly ever.
- Typical Placement: Adverbs of frequency have more specific placement rules. They are often located directly before or after the main verb.
- Between the subject and the main verb:
- "I always drink coffee in the morning."
- "She never eats meat."
- After the verb 'to be':
- "He is often late for meetings."
- "They are rarely sad."
- At the beginning or end of a sentence (less common for most, but some like sometimes, occasionally can be):
- "Sometimes, I go for a run."
- "We visit our grandparents weekly."
- Between the subject and the main verb:

Key Differences Summarized
The table below highlights the primary distinctions between adverbs of time and frequency:
| Feature | Adverb of Time | Adverb of Frequency |
|---|---|---|
| Primary Function | Indicates when an action happened | Indicates how often an action happens |
| Question Answered | When? For how long? Until when? | How often? How frequently? |
| Core Concept | Specific moment, period, or duration | Regularity, repetition, or habit |
| Common Examples | yesterday, now, later, soon, last week, daily | always, often, never, sometimes, weekly, annually |
| Typical Placement | Usually at the beginning or end of a sentence; sometimes before the main verb | Often between the subject and the main verb; after 'to be' verbs |
It's important to note that some adverbs, like daily, weekly, or annually, can function as both, depending on the context. If "daily" refers to when something happens (every day), it's time. If it refers to how often something happens (with daily regularity), it's frequency. The context of the sentence clarifies its role.
