Question 1

How do uncountable nouns work with subject-verb agreement?

Accepted Answer

Uncountable nouns always take a singular verb because they have no plural form. Common examples include "information" (The information is useful), "water" (The water is clean), "furniture" (The furniture looks new), "advice" (Her advice was helpful), and "money" (The money is in the bank). Many learners make mistakes with these nouns because they refer to large amounts — but grammatically, they are always singular. You cannot say "The informations are" or "The furnitures are." If you want to count them, use a countable phrase: "two pieces of furniture," "three items of information."

Question 2

What is the difference between "the number of" and "a number of"?

Accepted Answer

"The number of" refers to the total count itself and takes a singular verb: "The number of students is increasing" — the subject is "the number," which is one thing. "A number of" means "several" or "many" and takes a plural verb: "A number of students are absent" — the meaning is "several students are absent." This difference is tested frequently in grammar examinations because it catches learners who match the verb to "students" in both cases. Remember: "the number" equals singular (the count itself), "a number" equals plural (meaning several).

Question 3

Why does "every" make a subject singular?

Accepted Answer

"Every" means "each one individually" — it focuses on individual members rather than the whole group. Because it refers to one at a time, it always takes a singular verb: "Every shop closes at six" means "each individual shop closes." This applies even when "every" is followed by a plural-sounding phrase: "Every one of the answers is correct" — the subject is "every one," not "answers." The word "each" works in the same way: "Each student brings a packed lunch." Both "every" and "each" are always singular in English, and confusing them with plural forms is a common error at A2 level.
