What part of speech is “annually”

an adverb is a part of speech that modifies or describes verbs, adjectives, and other adverbs. Annually describes or modifies when something happens, typically meaning that the action or event is repeated or done every 12 months.

the rules and use cases for using annually as an adverb include using it to indicate a schedule or frequency for an action or event.

1. I get my car serviced annually.

2. The company holds a conference annually.

3. We revisit our budget annually.

a common mistake to avoid when using annually as an adverb is keeping unnecessary words away from it; for example, writing 'I get my car serviced on an annual basis' is incorrect, as annual basis is redundant.
