多此一举...

You can use it as a standalone comment. You can also use it to describe a specific decision. It often follows the verb 是 (to be). For example, 'That was 多此一举.' It’s a great way to point out inefficiency. Use it when someone overcomplicates a simple task.

Use it when a friend brings an umbrella on a sunny day. Use it in a meeting when someone suggests a redundant report. It’s perfect for those 'Why did you even do that?' moments.

• At a restaurant: Someone orders water when there is a free pitcher on the table.
• Texting: Sending a 'Did you get my text?' message five seconds later.
• At work: Printing an email that everyone already read online.

Don't use it if someone is being genuinely thoughtful. If your partner buys you flowers, don't say it's 多此一举. That’s a fast track to the doghouse! Avoid it when someone is being extra cautious for safety reasons. It can sound a bit critical or dismissive. Use it with people you know well to avoid sounding rude.

This phrase is a classic 'Chengyu' (four-character idiom). It comes from an ancient story called 'Drawing a Snake and Adding Feet.' A man finished drawing a snake first in a contest. He felt so confident he added feet to the snake. He lost because snakes don't have feet! It teaches us that 'more' isn't always 'better.'

You might hear 画蛇添足 (huà shé tiān zú). This is the specific idiom about the snake's feet. 多此一举 is the more modern, everyday version. Both mean 'superfluous.' Another casual way is saying 没必要 (méi bì yào), which just means 'unnecessary.' But 多此一举 has more 'flavor' and punch.
