Adverbs of frequency are used to indicate how often something occurs. Some common adverbs of frequency are: always, sometimes, frequently, occasionally, usually, seldom, normally, rarely, generally, hardly ever, and often. Adverbs of frequency are typically placed before verbs, except for the verb "to be" which they follow, or they can be placed at the beginning or end of sentences containing verbs like usually, normally, sometimes and occasionally. They are also placed between auxiliary and main verbs in sentences containing multiple verbs.
