Fast vs Quickly

Neither sentence really does a lot for me but they're both correct.

"Fast" is an adjective and an adjective should always modify a noun.

"Quickly" is an adverb. An adverb can modify a verb, an adjective or another adverb.

In your test case, "quickly" is the better choice. "Quickly" modified "received", a verb.

Using "fast" is incorrect.

Which proves that I should not be giving advice on grammar.

I've aced all my written assignments at uni. But I normally edit them several dozen times.

Wilso, you have other charms and talents.

Noddy,

I am a little confused here. Fast is also an adverb and can be used with verb, right?

By the by, welcome to A2K.

Off hand, I can't come up with an instance of "fast" acting as an adverb. Cars are fast. Loose women are fast. Square knots are fast. In each case "fast" is modifying a noun.

Can you give me a case in which it modifies a verb?

Remember, I said your original example was incorrect because "fast" is an adverb.

Noddy24,

I've just type the exact phrase "do it fast" in google.com and it turned about 44,000 results. You my try it here:

By the way, thanks for your reply. But the point I really need to know hereis the difference between "fast" and "quick".

Thanks.

Supposedly 50,000,000 Frenchmen can't be wrong, but believe a purist of an English teacher, 44,000 Google citations can be incorrect. "Do it fast" is an idiom, an example of informal English. It is not correct in formal situations.

As for your second question, "quick", like "fast" is an adjective. "Quickly" is the adverbial form.

Ask4help, Noddy is right. "Do it fast" is wrong. It doesn't matter how many hits you get on Google.
