お酒 (alcohol) は多く (too much) ないですよ

[magnus_scheving]

For what need mattaku here?

[amrok]

Not required.

[Kana332264]

全く is an adverb that puts emphasis on the adjective.

[Keith773734]

I wholeheartedly agree Duo.

[Juliano94]

Why can't it be あまり instead of まったく here?

[antypantyhose]

Why is there is 多く? Cant use まったくない?

[YAYOyamasa]

まったくない means there isn't any alcohol so it's wrong.

[Kana332264]

Because 全く is an adverb that enhances 多くない

[YAYOyamasa]

よisn't the necessary part of this sentence,with or without it the whole idea doesn't change.

[Kana332264]

Well, no, not really. Just saying "There isn't a lot of alcohol" is a statement. "There isn't a lot of alcohol, you know" can be used to cide someone for overindulging, for instance.

[Kana332264]

I'd say お酒があまりではありませんよ should be acceptable as well.
