Adverbs of frequency
We use adverbs of frequency with the present simple to talk about how often something happens.
Adverbs of frequency go before the verb, but after the verb be.
In negative sentences the adverb of frequency goes after don’t/doesn’t:
- We don’t often go to bed late.
- He doesn’t always agree with me.
In questions, adverbs of frequency go after the subject.
- Is he always late?
- Do they often go to the library?
The adverbs never and hardly ever (=almost never) have a negative meaning, but they are used with a positive verb:
- He is never late.
- He isn’t never late.
- They hardly ever go to the library.
- They don’t hardly ever go to the library.
Expressions of frequency
There are other expressions that we use to talk about frequency: once a day, twice a week, three times a month, every day, etc. These expressions are longer (2 words or more) and they go at the end of the sentence.
