Adverbs are words that modify verbs, adjectives, or other adverbs, providing more detail about how, when, where, why, or to what extent something happens. They can describe manner (how), time (when), place (where), frequency (how often), or degree (to what extent).
For example:
- Manner: She sings beautifully (how she sings).
- Time: He will arrive tomorrow (when he will arrive).
- Place: They looked everywhere (where they looked).
- Frequency: She often visits her grandmother (how often she visits).
- Degree: He is very tall (to what extent he is tall).
Adverbs often end in -ly, but not exclusively; for example, "fast," "well," and "very" are also adverbs.
