Question

In the following sentence, which word is the adverb?

It is said that Vincent van Gogh painted beautifully.

A.
that

B.
beautifully

C.
said

D.
painted

Answer 1

B beautifully. the word describes or modifies the action of painting, in this case of the great Dutch Master.

In modern day speak, there'd be a tendency to say that he "painted good". Since "good" is an adjective, the grammar there would be incorrect, but in modern day speak few seem to either be aware or to over much care.
