Adjectives, in Anglo-Saxon, have one set of strong and one set of weak
endings for each gender. The latter are used when the adjective is
preceded by the definite article or some word analogous thereto. Hence,
there are two declensions: the _definite_ and the _indefinite_.
Degrees of quantity or quality in adjectives are shown by comparison.
They are regularly compared by suffixing to the theme of the primitive
_ir_, _er_ or _or_ for the theme of the comparative, and _ist_, _est_ or
_ost_ for that of the superlative.
