A self-important person behaves as if they are more important than other people. They may interrupt, name-drop, or correct you in a way that says “I know better.” The word is always unkind: you use it when you disapprove.

A self-important person一個 self-important 的人 behaves表現得 as if they are好像自己 than other people比別人 more important更重要。 They他們 may可能 interrupt插嘴、name-drop搬出認識的大人物，or correct you或糾正你，in a way that says用一種在說 “I know better”「我比你懂」的方式。 The word這個字 is always unkind永遠不客氣：when you disapprove當你不以為然時 you use it才用它。

It does not mean the person is important. It means they act as if they are, and that act bothers you.

It它 does not mean不是說 the person is important這個人真的重要。 It means它是說 they他們 act as if they are裝得好像自己很重要，and that act而那副樣子 bothers you讓你不舒服。

Though actually, the same person may be kind in private and self-important in a meeting — the word is about the behaviour you can see, not their whole soul. It is a little formal; in easy talk people say stuck-up, full of themselves, or that someone thinks they are a big deal.

Though actually不過其實，the same person同一個人 in private私下 may be kind可能很和善，in a meeting在會議上 and self-important卻 self-important——the word這個字 is about講的是 the behaviour you can see你看得到的行為，not their whole soul不是他整個人的靈魂。 It它 is a little formal有一點正式；in easy talk輕鬆講話時 people人們 say會說 stuck-up、full of themselves，or that someone thinks they are a big deal或說某人自以為是號人物。
