naughty是个贬义词吗

是贬义词，意思是淘气的、顽皮的，例如：

1.It is unfair to label a small baby as naughty.硬说一个小小的婴儿淘气是不公平的。

2.You can guarantee the children will start being naughty as soon as they have to go to bed.孩子一到该上床睡觉时一定就不听话了。

3.I'm being very naughty ─ I've ordered champagne!我今天放肆一回——我要了香槟了！

《2》

不是贬义词，应该是中性词，可褒可贬，随语境的变化而不同，中文意思是adj. 顽皮的，淘气的；不妥当的，（成人）没规矩的；下流的，淫秽的；<古>邪恶的
