Why use "arbitrary" as an adverb in the following expression:

an arbitrarily large number

taken from wiktionary.

Where is the verb?

  • That is not a sentence. A sentence needs to have at least a subject and a verb. Therefore, this is not a sentence.

There is no verb.

The adverb "arbitrarily" is modifying the adjective "large".

Adverbs can modify verbs, but they can also modify adjectives, determiners, or other adverbs.

an extremely busy person
