Old English Morphology

a typical synthetic or inflected;
parts of speech: the noun, the pronoun, the adjective, the numeral, the verb, the preposition, the conjunction, and the interjection;
the nominal parts of speech had certain grammatical categories.
Old English

Categories:
gender (not grammatical): stān 'камень' (м.р. -a-), scip 'корабль' (ср. -a-), fōr 'поездка' (ж.р. -ō-), hond 'рука' (ж.р. -u-); info about the gender was encoded in different attributes (pronouns, adjectives);
number (plural vs. singular; rather stable);
case: nominative, genitive, dative and accusative (many homonymous forms).
The Noun in Old English

nouns had an elaborate system of declensions;
nouns were grouped according to: the former stem-forming suffixes and to some extent gender;
vocalic stems, a-stems, i-stems; consonantal stems, n-stems; ja-stems, nd-stems; 'root-stems');
the majority of OE nouns belonged to the a-stems, ō-stems and n-stems).
Morphological classification of nouns

The declension of a-stem nouns

personal,
demonstrative,
interrogative,
indefinite
The pronoun in OE

3 persons, 3 numbers: singular, plural and the remains of the dual number in the second person, 3 genders, 4 (5) cases;
the genitive case of personal pronouns: used as an object, or an attribute (like modern possessives): sunu mīn, his fæder (his son, his father);
no separate class of possessive pronouns;
personal pronoun+self: served as reflexive: him selfum.
Personal pronouns

the prototype of NE that: sē (m.), ðæt (n.), sēo (f.)
the prototype of NE this: ðes (m.), ðis (n.), ðēos/ðīos (f.).
indicated the noun's number, gender and case;
sometimes their meaning was weakened and approached the function of an article.
Demonstrative pronouns

hwā (m., f.) hwæt (n.) had a four-case paradigm (‘who, what’);
the Instrumental Case of hwæt – a separate interrogative word hwy (‘why’). I
Interrogative pronouns

numerous;
simple and compound:
ān ‘one, any’,
nān ‘none’ = ān+ negative particle ne;
nānþin ‘nothing’= nān + þin
Indefinite pronouns

the number of adjectives in Old English is not very significant.
Categories: number, gender, case + purely adjectival (the degrees of comparison– the positive, the comparative and the superlative).
The Adjective in OE

made synthetically, by adding suffixes -ra and -ost/-est: soft – softra – softest;
NO ANALYTICAL FORMATIONS;
suffixation could be accompanied by i-mutation of a root vowel: eald – ieldra – ieldest (old), stronʒ– stren ʒa – strenʒest.
four adjectives in Old English had suppletive degrees of comparison: ʒōd – betera – betst (good), yfel – wiesra – wierest (bad), mycel – māra – mæst (much), lytel – læssa – læst (little).
The degrees of comparison

strong and weak (the difference both formal and semantic)
most adjectives could be declined in both ways;
strong declension: used predicatively, used attributively without any determiners;
weak declension: was preceded by a demonstrative pronoun or the Gen. case of personal pronouns (determiners).
OE Adjective Declensions

finite and non-finite forms (infinitive and two participles);
categories (tense, mood, number, person);
the morphological classification: strong and week verbs;
the stems of the verb.
The OE Verb

being a verbal noun by origin it had the grammatical category of case;
the nominative –an, -ian (often used with such verbs as willan, sculan, weorðan to render various grammatical meanings;
the dative (suffix -enne/anne: writan – to writenne; the preposition to was associated with the dative case and used to indicate the direction or purpose of an action).
The non-finite forms: Infinitive

Participle I: the root + -ende (writan – writende ‘to write, writing’); was active in meaning;
Participle II: strong verbs: vowels interchange in the root + –en, weak – the dental suffix -d/t; was passive in meaning;
The non-finite forms: Participles

person, number, tense and mood;
number (singular and plural, a form of agreement between the subject and the predicate);
person (three persons), though the opposition is neutralised in many positions;
mood: Indicative – Subjunctive – Imperative;
tense: the opposition of past – non-past.
For future time reference: adverbs of future time, by the use of special verbs like the verbs of wishes and commands; the verbs willan, sculan, etc.).
The categories of the verb

it determined the application of form-building means in various groups of verbs;
strong verbs, weak verbs, preterite-present verbs; anomalous verbs and some other minor classes.
The morphological classification of OE verbs

Strong verbs
about 300 in Old English;
native verbs of Proto-Germanic origin; developed as the result of vowel alternation (ablaut);
the number of strong verbs in Germanic was steadily being reduced.
Weak verbs
more than strong and constantly growing;
the use of the dental suffix;
among the weak verbs there were derivatives of OE noun and adjective stems and also derivatives of strong verbs built from one of their stems.
Strong and weak verbs

strong and weak verbs are further subdivided into a number of morphological classes;
strong verbs are divided into seven classes on the basis of the differences in vowel gradation; Classes 1 and 3 were the most numerous of all, Class 2 included almost 40 verbs. The rest had from 10 to 15 verbs each.
weak verbs are divided into three classes depending on the ending of the infinitive, the sonority of the suffix and the sounds preceding the suffix.
Strong and weak verbs

combine the qualities of the strong verbs as well as the weak ones:
their present tense is formed according to the rules of formation of the past tense of the strong verbs (gradation or vowel interchange);
their past tense has all the peculiarities of the weak verbs;
participle II meanwhile retains the suffix -en of the strong verbs.
12 of them in OE;
six of them have survived in Mod E: they are Modern English modals.
Preterite-present verbs

with irregular forms:
bēon/wesan ‘be’,
ʒan ‘go’,
dōn (do)
willan ‘will’.
Anomalous verbs

derived from a set of ‘stems’ or principal parts of the verb:
the Present tense;
the Past Tense stems;
the Past Participle stem.
Strong verbs
beran bær bæron ʒeboren ‘bear’
dēman dēmde dēmed deem
Verbal stems

Syntax
a synthetic language the functional load of syntactic ways of word connection was relatively small;
mostly spoken the written forms resembles oral speech; simple syntax.

Sōđlice sum mann hæfde twēʒen suna
Truly a certain man had two sons the connection between the parts of the words is shown by the forms of the words;
some parts of the sentences that are obligatory for NE could be omitted;
multiple negation (ne+ nāht or nōht).
Simple Sentence

existed since the earliest times;
though the structures were numerous, they were a bit clumsy and not very precise;
coordinate, subordinate, asyndetic connection.
Compound and Complex Sentences

relatively free, influenced by logical and stylistic factors;
the freedom of word order should not be overestimate (question vs. statements)
Hwæt sceal īc sinʒan?
What shall I sing? (partial inversion)
Hēr cuōm sē here tō Rēadinʒum…
In this year came that army to Reading (full inversion, after an adverbial modifier)
Word Order

Ōhthere sǣde his hlāforde, Œlfrēde cyninʒe þæt hē ealra Norđmonna norþmest būde
Ohthere said (to) his lord Alfred king that he (of) all Northman to the North lived (had lived)
(the subject in the subordinate clause is followed by the connective and ends with the predicate)
