• Which one should I use?

    1. Play music loud
    2. Play music loudly

      • I think "play music loudly" is right but "play music loud" is used more. Please tell me your opinion and the reason why you choose it. Thank you so much.

      • Maybe my grammar is wrong 'cause I'm not good at English

  • "Play loud music", not "play music loud" – user180089 Jul 17 '16 at 15:13

    @V0ight I searched on Google and saw "play music loud" is right. I heard in the lyrics of Florida's song - My house: "play that music too loud" – Nguyen Ngoc Bich An Jul 17 '16 at 15:30
  • I suppose it is right, my mistake. I still prefer the latter and would use it unconditionally; the former just sounds wrong to my ears. – user180089 Jul 17 '16 at 16:01

    The reason loudly is the "more correct" option is that you can't use loud as an adverb in all contexts, e.g. "He was loud playing the music as he walked with his radio on his shoulders". It can only be loudly in this specific context. So be careful to understand this as English is a fickle language. – user180089 Jul 17 '16 at 16:07

Normally, adjectives are turned into adverbs by adding the -ly suffix to them.

But some words are used as both adjectives and adverbs, with no discernable difference in their form. For example,

  1. I like fast cars. [adjective]
  2. He drove fast. [adverb]

  3. They played a clean game. [adjective]

  4. They played clean. [adverb]

"Loud" is an example of a word that can be used as both an adjective and an adverb. For example, people say:

  1. I like loud music. [adjective]
  2. I play music loud. [adverb]

If you look at this google books search, you'll see plenty example of it being used as an adverb. Further, Oxford Dictionaries even lists it as an adverb.

But some people also use the clearly adverbial form "loudly", as in

  1. I play music loudly. [adverb]

In conclusion, both "loud" and "loudly" can be used as adverbs. The choice is yours.

  • Thank for your help. I have always thought "loud" is used as an adjective. – Nguyen Ngoc Bich An Jul 17 '16 at 15:38
  • It mostly is, but it can also be used as an adverb. – GrimGrom Jul 17 '16 at 15:39
