Uncountable Nouns – Is Lemonade Countable or Uncountable?

There is little to memorize about this topic; your intuition should be enough. But do memorize these two things:

1. Countable nouns can be changed into uncountable nouns:

   • She fed the baby a teaspoon of apple.
   • Blend the slices of mango in a mixer to turn them into juice.

   Uncountable nouns can be changed into countable nouns:

   • There are several new butters being produced without milk.
   • Can I have two sugars, please?

2. You can have a noun being treated as both collective and singular in the same sentence (George Yule, Explaining English Grammar. Oxford, 1998):

   • The family HAS decided THEY can't afford a big wedding.
   • The audience WAS cheering and clapping THEIR hands.

In some instances, it's countable and in other uncountable, depending on its meaning. According to the Longman dictionary if it means "something that happens to you or something you do especially when this has an effect on what you feel or think", it's countable.Seeing the grand Canyon, of course, has a great effect on everybody, so in this case it's countable and you should say: "Seeing the Grand Canyon was certainly an experience". More examples:

Ballooning is quite an experience.

I have a lot of experiences from trip to Africa.

Seeing the Grand Canyon was a really fantastic experience.

But if it means "knowledge or skill that you gain from doing a job or activity", it's uncountable.
