Puzzling Plurals: A pair of…

Lesson:

The noun that appears after a pair of is not considered during subject/verb agreement.  Here’s why: your verb agrees with the singular word pair.  Even though pair actually means two, the word pair is singular (as signaled by the article a).

Examples:

  • A pair of glasses is on the counter.
  • A pair of jeans costs about $50 at the department store.

Notes:

If use the plural subject and not the expression a pair of, your verb generally agrees with a plural subject.

Examples:

  • Glasses are on the counter.
  • Jeans cost about $50 at the department store.

Reminders:

Plurals make a BIG difference in your speech and writing when it comes to four things:

  • adding, pronouncing, and spelling the –s ending with plurals,
  • determining the count or non-count status of your noun,
  • deciding which article to use (if any), and
  • subject/verb agreement.  Do you know that –S you add to your verb when the subject is (or can be replaced with) he/she/it?  That’s an example of subject/verb agreement.

Oh, yea, don’t forget!  Just because you add an –s to verbs, it doesn’t mean they’re plural.  Verbs can’t be plural—only nouns can be plural.
