CHAPTER XII.
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.
