THE CARDINAL NUMBERS.
§ 261. Generally speaking, the greater part of the cardinal numbers are
undeclined. As far as _number_ goes, this is necessary.
_One_ is naturally and exclusively _singular_.
_Two_ is naturally _dual_.
The rest are naturally and exclusively _plural_.
As to the inflection of gender and case, there is no reason why all the
numerals should not be as fully inflected as the Latin _unus, una, unum_,
_unius_. It is a mere habit of our language that they are not so in
English.
