Questions & Answers about zhège xǐyīchéngxù cuò le.

What is the basic structure of this sentence?

The structure is:

这个洗衣程序 + 错了
this washing program + is wrong / has gone wrong

So the sentence is basically:

• subject/topic: 这个洗衣程序
• predicate: 错了

A very literal gloss would be:

this washing-program wrong LE

Mandarin often lets a word like 错 act directly as the predicate, so you do not need an extra word like is in the same way English does.

Why is it 这个? What does 个 do here?

这个 is made up of:

• 这 = this
• 个 = a very common classifier / measure word

In Mandarin, when a demonstrative like 这 or 那 comes before a noun, you usually need a classifier:

• 这个程序 = this program
• 那个按钮 = that button

Here, 个 is the general classifier used with 程序 in everyday speech.

So 这个洗衣程序 means this washing program / this wash cycle.

Could I say 这洗衣程序错了 without 个?
