Jo’s question: “Which is correct? ‘There was lightning and thunder last night,’ or ‘there were lightning and thunder.’ ”
BizWritingTip response: This question relates to subject and verb agreement. When a sentence begins with there or here, the actual subject is considered to be the word or words following the verb. Use a singular verb if the actual subject is singular and a plural verb if the actual subject is plural.
There are three proposals to be written. (Proposals — the actual subject— is plural so the verb is are.)
Here is the signed agreement. (Agreement — the actual subject— is singular so the verb isis.)
There was lightning last night. (Lightning is singular so the verb is was.)
When you see the word “and” in the subject, it is called a compound subject. Always use a plural verb with a compound subject.
There were lightning and thunder last night. (Lightning and thunder form a compound subject so the verb is plural.)
Frankly, although this is grammatically correct, it sounds awkward. I would rewrite the sentence.
We had thunder and lightning last night.
The same rule (when “and” is in the subject, the verb is plural) holds true even if the sentence does not start with there or here.
Thunder and lightning are expected today.
