I'd like to know why the answer is "loud and clear".These are the adjs.I think the answer is "loudly and clearly" in order to be adverbs.

I answered this in your duplicate post, May. As an addendum, loudly and clearly would work here grammatically, but not idiomatically.

I don't understand your answer. It is the gramma English test, so i think the correct answer should be "loudly and clearly"

Hi Fairy,

You are quite correct in saying that loudly and clearly are the adverbs, which usually qualify the verb. Grammatically in this sentence the two adverbs would be used but this has become used so often as an expression: I can hear you loud and clear - (I can hear you very well) that it has now become idiomatic and so doesn't follow the usual rules of grammar.

Hi,

'Loud and clear' is the accepted idiom.

Have you ever heard of aloudly? Aloud is just a predicative adjective and can't be an adverb. Moreover, aloud is just used to modify speaking volume-say or speak or shout not hear.
