Question

There _ any sugar in the glass. Aren’t or isn’t

Answer 1

There isn't any sugar in the glass

Step-by-step explanation:

"Isn't" is singular, whereas "aren't" would be plural. Sugar is singular, therefore the answer is "isn't".

Answer 2

The answer is “isn’t.”
“Isn’t” and “aren’t” are just like “is” and “are.”
“Is” is for singular and “are” is for plural. That’s the most common way to know which one to use between these two. Another way is that “isn’t” is also for “uncountable” and “aren’t” is for countable.
For example: “There isn’t enough time.”
Here, time is uncountable, so you will use “isn’t.
Example for “aren’t”: “There aren’t any coins left.”
Here, coins are countable, so you will use “aren’t.”

In this given problem, sugar is uncountable.
