Emma,

Thank you for the question.

When I said "a concept that doesn't exist in English" I meant
that dual - in the sense of a word having a different form depending
on whether there are two are many - is not found in English.

The wording may have been bad.

vit = we two
vér = we (more than two)

þit = you two
þér = you (more than two)

>The construction "you two" or "we two" is actually used quite often. It is

Yes, interesting. One wonders where exactly the boundary lies:)

we two (normal)
we three (normal)
we four (abnormal??)
we five (abnormal?)
