An adverb is a word that modifies or describes a verb, an adjective, another adverb, or even an entire sentence. It provides additional information about how, when, where, to what extent, or how often something happens. For example, in "he sings loudly," the adverb "loudly" modifies the verb "sings" by describing how he sings

. Adverbs often end in -ly (such as "quickly," "badly"), but some do not (such as "fast," "well"). They can express various aspects including:

• Manner (how something happens): quickly, carefully
• Time (when something happens): yesterday, soon
• Place (where something happens): here, abroad
• Degree (to what extent): very, almost
• Frequency (how often): always, rarely
• Purpose or reason : why something happens
• Conjunctive adverbs : linking ideas between sentences, such as "however," "therefore"

Adverbs can modify:

• Verbs : She runs quickly.
• Adjectives : The movie was very interesting.
• Other adverbs : He sings quite beautifully.
• Whole sentences : Fortunately , we arrived on time

In summary, an adverb adds detail and context to other words or sentences, answering questions like how? , when? , where? , to what extent? , and how often? to enrich meaning and clarity in communication
