Degrees of Comparison
Like adjectives in other languages, most OE adjectives distinguished between three degrees of comparison: positive, comparative and superlative. The regular means used to form the comparative and the superlative from the positive were the suffixes -ra and -est/ost. Sometimes suffixation was accompanied by an interchange of the root-vowel.
The adjective god had suppletive forms. Suppletion was a very old way of building the degrees of comparison:
god – bettra – bet(e)st,
lytel – læssa – læst.
The pronoun
OE pronouns fell roughly under the same main classes as modem pronouns: personal, demonstrative, interrogative and indefinite. As for the other groups — relative, possessive and reflexive — they were as yet not fully developed and were not always distinctly separated from the four main classes. The grammatical categories of the pronouns were either similar to those of nouns (in "noun-pronouns") or corresponded to those of adjectives (in "adjective pronouns"). Some features of pronouns were peculiar to them alone.
Personal Pronouns*
OE personal pronouns had three persons, three numbers in the 1st and 2nd p. (two numbers—in the 3rd) and three genders in the 3rd p. The pronouns of the 1st and 2nd p. had suppletive forms like their parallels in other IE languages. The pronouns of the 3rd p., having originated from demonstrative pronouns, had many affinities with the latter.
In OE, while nouns consistently distinguished between four cases, personal pronouns began to lose some of their case distinctions: the forms of the Dat. case of the pronouns of the 1st and 2nd p. were frequently used instead of the Acc.; in fact the fusion of these two cases in the pi was completed in the WS dialect already in Early OE: Acc. eowic and usic were replaced by Dat. eow, us; in the sg usage was variable, but variant forms revealed the same tendency to generalise the form of the Dat. for both case's. This is seen in the following quotation:
Se ðe me gehælde, se cwæð tō me 'He who healed me, he said to me' — the first me, though Dat. in form, serves as an Acc. (direct object); the second me is a real Dat.
