Is there any rule in the adverb sequence?So Can I use quickly,clearly and hard at the begining of sentence,at the end of the sentence or at between subject and verb?Is it right?Adverb sequence is not important in the sentence?

Answer 1

"Hard" is not an adverb.

Adverbs do not have to modify verbs only.
In a sentence, they should be located close to the word they modify. You just can't stick them anywhere.

It would be easier to explain if you had an example.
