The reciprocal pronoun each other is used to identify mutual actions or feelings between two people or things. An example of the usage you’re probably familiar with is “we love each other.” If you were to describe the photo below, you might write the following:
The cheetah on the right licked the cheetah on the left, while the cheetah on the left licked the cheetah on the right.
That sentence describes the picture but is wordy. Instead, you could use a reciprocal pronoun as follows:
The cheetahs licked each other.
Using reciprocal pronouns is helpful when you are trying to make your writing more concise. For example, consider the following sentence:
He saw me, and I saw him.
It is clearer to write it as follows:
We saw each other.
Let’s look at two more sentences.
George hates Larry. Larry hates George.
Again, as the following sentence demonstrates, a reciprocal pronoun is clearer and less wordy:
George and Larry hate each other.
You could even write the following:
They hate each other.
The reciprocal pronoun each other is often used with the pronouns we and they.
Julie spends the night at Lisa’s house often, and Lisa often spends the night at Julie’s house.
This sentence is wordy and needs to be streamlined. We can make this change as follows:
Julie and Lisa often spend the night at each other’s house.
Determining whether the noun that follows each other's is plural or singular is simple. Does each girl have more than one house? No, so house should be singular.
Now you try. For each sentence below, determine whether the missing pronoun is each other or each other’s. Respond by clicking on one box for each question.
