In all cases, an Adverb describes a Verb, Adjective, or another Adverb. For example, “quickly” is an Adverb that may be used to describe the speed of action. It is often used in sentences like, “He quickly runs”. But today, we are discussing Adverbs of Frequency. Adverbs of Frequency describe how often an event occurs.
There are two types of Adverbs of Frequency, definite and indefinite. Definite Adverbs of Frequency give the exact time of an event, such as hourly. For example, you may hear a native English speaker say, “The train arrives, hourly”. But, Indefinite Adverbs of Frequency are abstract. “Always” is an Indefinite Adverb of Frequency, a few things always happen.
