In last week’s discussion, we looked at sentences in which reference is made to two people by way of description but which may be referring to just one person.
We said, for instance, that the expression:
My brother and my sister....
refers to two people, for which reason we have to use a plural verb, as in:
My brother and my sister have travelled outside the country.
But the expression:
My brother and sister.....
refers to only one person, for which reason we must use a singular verb, as in:
My brother and sister has travelled outside the country.
If we write or say:
My brother and sister have travelled outside the country
it is incorrect, grammatically speaking, because we have used a plural verb for a singular subject, even though we have made mention of two people.
It is for this same reason that the following sentences are incorrect:
- The boy and girl attend the same school.
- A man and woman are here to see you.
- The house help and sister have not been seen this morning.
- The book and pencil belong to Lillian.
- The Prince and Princess live in the castle.
If each of these sentences does actually refer to two people, then both items of description must be preceded by determiners — words that are used before nouns in order to show which thing you mean.
Determiners include a/an, the, some, my, his, your, etc.
So for sentence 1. above to be correct, we must precede the noun girl with the determiner the, to make the sentence read:
The boy and the girl attend the same school.
We can correct the other sentences in the same manner:
- A man and a woman are here to see you.
- The house help and her/my/your/our sister have not been seen this morning.
- The book and the pencil belong to Lillian.
- The Prince and the Princess live in the castle.
Always bear in mind this principle: if you mean to talk about two different people, always precede both nouns with determiners.
On the other hand, if you are talking about one person whom you describe in two ways, then only the first noun must have a determiner.
So the following refers to one person:
my senior and friend
our friend and church member
your brother and classmate
the pastor and choirmaster
the founder and financier
the headmaster and patron of the club
the senior prefect and captain of the school team
In complete sentences, each of these expressions must agree with a singular verb because each expression is grammatically singular.
The senior prefect and captain of the school team has won a scholarship to study abroad.
Your brother and classmate is always late to school.
