關於adj的問題想請教一下

environmentally friendly
這個environmentally是個副詞


副詞只可用來修飾名詞以外的東西，如修飾形容詞，副詞，動詞，分詞，甚至句子

如：she was laughing happily(happily就是用來修飾laugh這動作）

所以，environmentally絕對不是用來修飾spray，而是修飾friendly，意思是說出，究竟對甚麼friendly，是對環境。


World peace is a very commonly debated subject.
中的commonly是用來修飾debated這個分詞（這分詞有形容詞功用）

希望幫到你！

environmentally friendly is 100% correct.

The adverb environmentally is used to qualify the adjective friendly.

"environmental friendly" is wrong.

Another very commonly heard of phrase is "politically correct", adverb qualifying the adjective.

You may say "environment friendly".
The hair spray is environment friendly.

Similar expression is "user friendly".
The new software is user friendly.

Strictly speaking, these words should be hyphenated but "user friendly" has been widely accepted.

World peace is a very commonly debated subject.
在這句中commonly是形容那個字？是否形容debated？
100%正確!

Make sure that the spray is environmentally friendly.
用environmentally是畫蛇添足，錯的。
你的理解正確，這個是形容the spray這物件。
實際說
Make sure that the spray is environmental friendly.
已經正確。
不過留意你串字，spray和environementally都串錯/手誤。
