Should it be singular or plural after “each other’s” here.
They touched each other’s nose.
They touched each other’s noses.
Are both correct?
John Lawler notes in another post that each other can be broken up. This would give us:
- They each touched the other's nose
- *They each touched the other's noses
However, this rewriting of the sentences seems to be slightly different, perhaps because of the definite article, the, before the word other's.
Of course, it's trivially true in relation to this question that the example (4) would be fine if people had several noses. The asterisk in the example indicates that this is not a grammatical means of indicating the same meaning as given in (1).
