# How to count “Chinese yam”

I am not sure if most westerners have seen or eaten this food. Here is a picture of Chinese yam:

.

As you can see in the picture, there are two sticks, but I am not sure if stick is a correct quantifier for Chinese yam. Which is the right one to go with it?

a. 2 Chinese yams
b. 2 sticks of Chinese yam
c. 2 Chinese yam tubers/taproots
d. 2 tubers/taproots of Chinese yam

I already posted an answer but then I found this, which is related but maybe not a dupe: english.stackexchange.com/questions/29225/… – Mr. Shiny and New 安宇 Nov 14 '11 at 14:31

Yam can be used as a countable noun (two yams) or an uncountable noun (two sticks of yam) though the latter sounds awkward as mentioned by the others.

In general most food is both countable and uncountable. It is countable when you refer to it in its intact form that you normally find it in.

For example:

Take two carrots and chop them

This means to take two whole carrots, as they are when pulled from the earth, and chop them. (Presumably you wash and peel them first, etc).

This soup has too much carrot in it.

This means that the soup contains too much carrot mass, that is, too many carrots were chopped for this soup (or, perhaps, the carrots were too large). So a whole carrot root, as pulled from the ground, is "one carrot", but it is made up of "carrot".

The same applies to many other food types. It gets complicated when a food doesn't have a standard unit, such as beef. You can't really say "two beefs" because nobody knows what that means. Two pounds? Two rib-eye steaks? You need some kind of measuring unit.

For celery, which is normally sold as a bunch of stalks, you have to say "two stalks/sticks of celery". For liquids you'd have to specify the measuring quantity, such as "two cups" or "two bottles" or "two tablespoons". Certain liquids might have a relatively standard serving size, or the serving size might not always matter, so you could hear

Give me two beers, please

which implies "Give me two beers in whatever normal serving size you use, be it bottles or cans or pint-glasses"

To get to the point for the vegetable in question, since it is probably sold as individual tubers, I'd assume that if you said "2 Chinese yams" then people would understand that as "2 Chinese yam tubers". It probably isn't necessary to say "tubers" and that would likely sound odd. I've never heard anyone say "Use two carrot roots".

As for your other suggestions, I'm not sure I would understand what you meant by "two sticks of Chinese yam", since it sounds like "stick" is some kind of measurement when in fact you meant to say "tuber". But "two tubers of Chinese yam" also sounds like you are using "tuber" as an official measurement, much like one would say "two kilograms of Chinese yam". I don't think a native speaker would be likely to say "two tubers of Chinese yam".

Most root vegetables are used alone: 2 radishes, 2 carrots, 2 parsnips, 2 potatoes, 2 sweet potatoes, 2 onions, 2 rutabagas, 2 beets, 2 yams. There are some for which you would use an additional word: 2 sticks of celery, 2 ears of corn, 2 heads of garlic, 2 pieces of fruit. There are probably other examples, but I think it sounds best to have it without the word "stick".

As you mentioned that there are some foods that would use an additional word. Could you specify what foods they are or which reference book or where one can refer to? By the way, the shape of celery is long which is similar to Chinese yam. Why is it no good to use stick to go with Chinese yam? What is the rule to apply to those foods then? – simplebeing Nov 15 '11 at 1:51
I'm sorry, I don't have a reference, but I have an idea. When there's no confusion about what you would be referring to when you say 2, then you can just say 2. But if there's some uncertainty, then you would say 2 plus another word. With garlic, if you didn't specify 2 heads, then you might be referring to 2 cloves. With celery, if you didn't specify 2 sticks, then you might be referring to 2 whole clumps. So with the yams, like a lot of root vegetables, there's no need for the additional word. – Julia Nov 16 '11 at 8:05
