And the adverb is defined as follows: an adverbial word whose main function is that of an adverbial determination, ie to express more detailed information about events or characteristics, and which typically has an unchangeable form.
I remember the definition of the adverb from a quote. In the movie Outbreak, Casey Schuler, played by Kevin Spacey, states:
“It's an adverb, Sam. It’s a lazy czech republic telegram screening tool of a weak mind.”
(Roughly translated: “It’s an adverb, Sam. A lazy tool of a weak mind.” In the dub, I think he says “accessory” instead of “tool.”)
No.
Check each one for more appropriate nouns or verbs. These are the words being described.
Compare: The “big house” becomes “the villa”. Or “the palace”.
Instead of "Paul ran quickly down the street," you write "Paul ran down the street." Or "rushed." Or "panted."
