7. Order of Adverbs (of manner)

Adverbs of manner most commonly come directly after intransitive verbs that they modify. If the verb is transitive, then the adverb must not immediately follow the verb; it can either come before the verb or after the direct object. For example:

“He speaks well.” (intransitive)
“She walked slowly.” (intransitive)
“Janet wrote the letter beautifully.” (transitive—correct)
“Janet wrote beautifully the letter.” (transitive—incorrect)

Rearranging the order
You may have noticed that in the second example we can put the adverb first: “She quickly walked” is perfectly correct, and it adds a bit more emphasis to quickly. The adverb can also come before a transitive verb, as in “Janet slowly sang a song.”

However, for simple sentences that don’t require extra emphasis, it is better to have the adverb come after the verb. (And, in some instances, the adverb can’t come first. For example, “he well speaks” is clearly incorrect.)
