Most people learning Mandarin Chinese get a bit confused with the words 半 (bàn), 一半 (yí bàn) and 一个半 (yí ge bàn). They're all used for talking about halves in one way or another, but the difference between them can be tricky at first.
None of the words we're explaining here are actually very hard to use. The problem is that they're similar, and you get interference. In other words, you get them mixed up. To try and help you avoid that with these words, we've put together the super-clear guide below.
To talk about *half of *something, the structure is:
半 + [measure word] + [noun]
It's as simple as that. Most often the measure word is the generic 个 (ge), but any measure word can and should be used in that slot. Let's have a look at some examples for this structure:
半个小时
半个三明治
半碗饭
半条鱼
Notice how in English you could say “half of” in all those situations, but usually you just drop the word “of”. However, it might be helpful to try and remember the Chinese 半个 as meaning “half of”.
Now let's have a look at some full example sentences for this structure:
我吃了半个苹果。
我只要半张纸。
我们花了半个小时做作业。
Notice the 半 + measure word structure in each of the sentences above. If a measure word comes after 半, then it means “half of” or “half a”. That makes it different to the other two words described below.
一半 is used without a measure word at all. Always remember that you can't put a measure word before or after 一半. There isn't a general structure for using 一半, because it's more of a standalone word meaning “a half” or “one half”. Let's have a look at some example sentences for 一半:
我们已经喝了一半了。
我吃饭吃了一半就不想吃了。
他总是把薪水的一半存入银行。
Hopefully you can see that it's easier to think of 一半 as a vocabulary item than a structure. This makes it different to 半 and 一个半, which you might want to think of as being more structural.
Finally, we come to 一个半 which means one and a half. The structure for this is:
一个半 + [noun]
You could think of 一个半 as being like 一个 (one) plus 半 (half), so altogether it makes one and a half. Also notice that it contains a measure word, so you don't add any more measure words to this structure! The 个 shown here can of course be replaced with any appropriate measure word.
Let's have a look at some example sentences for 一个半 (plus the same structure with other measure words):
这个产品很受欢迎 - 我们已经卖了一盒半了!
我拿了一张半纸。
我们花了一个半钟头才做完。
最大的鹰的翅膀展开长达一米半。
Hopefully you can see the 一 + measure word + 半 structure in each of the sentences above.
Now it's time for a quick summary of the difference between 半, 一半 and 一个半 in Chinese grammar.
