loud

[Allen165]

I'd like to know why it's "loud" and not "loudly."

The fans who didn’t flee at halftime remained out of morbid curiosity to see just how ugly it would get. Oh, and to boo. To boo loud and long, to let the Raptors know that efforts like the one they put out Friday night – or more correctly didn’t put out Friday night – are simply not acceptable.

To boo how? To boo loudly. No?

Thanks.

Yes, loudly, strictly speaking. But then, it's common for the adverb and adjective to be used interchangeably especially in spoken English. It's considered 'cool' I guess.;-)

Good morning, Jasmin.

(1) You have asked a great question.

(2) This is what I have found:

(a) To boo loud (so-called "flat adverb" ) or loudly (-ly adverb) would both be correct.

(b) One expert says that "loud" is often restricted to "a few simple and familiar verbs" such as: talk/scream/shout/cheer. I guess we could count "boo" in that category.

(c) Another expert explains that sometimes there is difference:

(i) Speak loud and distinctly. = refers to the volume of your voice.
(ii) He boasted loudly of his power. = does not necessarily refer to the loudness of his voice. It could mean that he was very emphatic or even offensive in proclaiming to everyone what power he held.

Have a nice day!
