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.

Demonstrative Pronouns

There were two demonstrative pronouns in OE: the prototype of NE that, which distinguished three genders in the sg and had one form for all the genders in the pi. and the prototype of this with the same subdivisions: ðes Masc., ðeos Fem., ðis Neut. and ðas pl. They were declined like adjectives according to a five-case system:

Nom., Gen., Dat., Acc., and Instr. (the latter having a special form only in the Masc., Neut.sg).

Declension of sē, sēo, ðæt

Case	Singular	Plural
	M N F	All genders
Norn.	sē, se ðæt sēo	ða
Gen.	ðæs ðæs ðære	ðāra, ðæra
Dat.	ðæm, ðām ðæm, ðām ðære	ðām, ðæm
Acc.	ðone ðæt ðā	ðā
Instr.	ðy, ðon ðy, ðon ðære	ðæm, ðām

The paradigm of the demonstrative pronoun se contained many homonymous forms. Some case endings resembled those of personal pronouns, e.g. –m – Dat. Masc. and Neut. and Dat. pl;

the element -r- in the Dat. and Gen. sg Fem. and in the Gen. pl. These case endings, which do not occur in the noun paradigms, are often referred to as "pronominal" endings (-m, -r-, -t).

The adjective. Grammatical Categories

As stated before, the adjective in OE could change for number, gender and case. Those were dependent grammatical categories or forms of agreement of the adjective with the noun it modified or with the subject of the sentence — if the adjective was a predicative. Like nouns, adjectives had three genders and two numbers. The category of case in adjectives differed from that of nouns: in addition to the four cases of nouns they had one more case, Instr. It was used when the adjective served as an attribute to a noun in the Dat. case expressing an instrumental meaning — e.g.: lytle werede 'with (the help of) a small troop'.
