Old English grammar

Strong verbs

Strong verbs use the Germanic form of conjugation known as ablaut. In this form of conjugation, the stem of the word changes to indicate the tense. Verbs like this persist in modern English; for example sing, sang, sung is a strong verb, as are swim, swam, swum and choose, chose, chosen. The root portion of the word changes rather than its ending. In Old English, there were seven major classes of strong verb; each class has its own pattern of stem changes. Learning these is often a challenge for students of the language, though English speakers may see connections between the old verb classes and their modern forms.

The classes had the following distinguishing features to their infinitive stems:

1. ī + one consonant.
2. ēo or ū + one consonant.
3. Originally e + two consonants. By the time of written Old English, many had changed. If C is used to represent any consonant, verbs in this class usually had short e + lC; short eo + rC; short i + nC/mC; or (g̣ +) short ie + lC.
4. e + one consonant (usually l or r, plus the verb brecan 'to break').
5. e + one consonant (usually a stop or a fricative).
6. a + one consonant.
7. Other than the above. Always a heavy root syllable (either a long vowel or short + two consonants), almost always a non-umlauted vowel – e.g., ō, ā, ēa, a (+ nC), ea (+ lC/rC), occ. ǣ (the latter with past in ē instead of normal ēo). Infinitive is distinguishable from class 1 weak verbs by non-umlauted root vowel; from class 2 weak verbs by lack of suffix -ian. First and second preterite have identical stems, usually in ēo (occ. ē), and the infinitive and the past participle also have the same stem.

The first preterite stem is used in the preterite, for the first- and third-person singular. The second preterite stem is used for second-person singular, and all persons in the plural (as well as the preterite subjunctive). Strong verbs also exhibit i-mutation of the stem in the second- and third-person singular in the present tense.

The third class went through so many sound changes that it was barely recognisable as a single class. The first was a process called 'breaking'. Before ⟨h⟩, and ⟨r⟩ + another consonant, ⟨æ⟩ turned into ⟨ea⟩, and ⟨e⟩ to ⟨eo⟩. Also, before ⟨l⟩ + another consonant, the same happened to ⟨æ⟩, but ⟨e⟩ remained unchanged (except before combination ⟨lh⟩).

The second sound change to affect it was the influence of palatal sounds ⟨g⟩, ⟨c⟩, and ⟨sc⟩. These turned preceding ⟨e⟩ and ⟨æ⟩ to ⟨ie⟩ and ⟨ea⟩, respectively.

The third sound change turned ⟨e⟩ to ⟨i⟩, ⟨æ⟩ to ⟨a⟩, and ⟨o⟩ to ⟨u⟩ before nasals.

Altogether, this split the third class into five sub-classes:

1. e + two consonants (apart from clusters beginning with l).
2. eo + r or h + another consonant.
3. e + l + another consonant.
4. g, c, or sc + ie + two consonants.
5. i + nasal + another consonant.

Regular strong verbs were all conjugated roughly the same, with the main differences being in the stem vowel. Thus stelan "to steal" represents the strong verb conjugation paradigm.

Weak verbs

Weak verbs are formed by adding alveolar (t or d) endings to the stem for the past and past-participle tenses. Examples include love, loved and look, looked.

Originally, the weak ending was used to form the preterite of informal, noun-derived verbs such as often emerge in conversation and which have no established system of stem-change. By nature, these verbs were almost always transitive, and even today, most weak verbs are transitive verbs formed in the same way. However, as English came into contact with non-Germanic languages, it invariably borrowed useful verbs which lacked established stem-change patterns. Rather than inventing and standardizing new classes or learning foreign conjugations, English speakers simply applied the weak ending to the foreign bases.

The linguistic trends of borrowing foreign verbs and verbalizing nouns have greatly increased the number of weak verbs over the last 1,200 years. Some verbs that were originally strong (for example help, holp, holpen) have become weak by analogy; most foreign verbs are adopted as weak verbs; and when verbs are made from nouns (for example "to scroll" or "to water") the resulting verb is weak. Additionally, conjugation of weak verbs is easier to teach, since there are fewer classes of variation. In combination, these factors have drastically increased the number of weak verbs, so that in modern English weak verbs are the most numerous and productive form, although occasionally a weak verb may turn into a strong verb through the process of analogy, such as sneak (originally only a noun), where snuck is an analogical formation rather than a survival from Old English.

There are three major classes of weak verbs in Old English. The first class displays i-mutation in the root, and the second class none. There is also a third class explained below.

Class-one verbs with short roots exhibit gemination of the final stem consonant in certain forms. With verbs in ⟨r⟩, this appears as ⟨ri⟩ or ⟨rg⟩, where ⟨i⟩ and ⟨g⟩ are pronounced [j]. Geminated ⟨f⟩ appears as ⟨bb⟩, and that of ⟨g⟩ appears as ⟨cg⟩. Class-one verbs may receive an epenthetic vowel before endings beginning in a consonant.

Where class-one verbs have gemination, class-two verbs have ⟨i⟩ or ⟨ig⟩, which is a separate syllable pronounced [i]. All class-two verbs have an epenthetic vowel, which appears as ⟨a⟩ or ⟨o⟩.

In the following table, three verbs are conjugated. Sƿebban "to put to sleep" is a class-one verb exhibiting gemination and an epenthetic vowel. Hǣlan "to heal" is a class-one verb exhibiting neither gemination nor an epenthetic vowel. Sīðian "to journey" is a class-two verb.

During the Old English period, the third class was significantly reduced; only four verbs belonged to this group: habban 'have', libban 'live', secgan 'say', and hycgan 'think'. Each of these verbs is distinctly irregular, though they share some commonalities.

Preterite-present verbs

The preterite-present verbs are a class of verbs which have a present tense in the form of a strong preterite and a past tense like the past of a weak verb. These verbs derive from the subjunctive or optative use of preterite forms to refer to present or future time. For example, ƿitan, "to know" comes from a verb which originally meant "to have seen" (cf. OE ƿise "manner, mode, appearance"; Latin videre "to see" from the same root). The present singular is formed from the original singular preterite stem and the present plural from the original plural preterite stem. As a result of this history, the first-person singular and third-person singular are the same in the present.

Few preterite-present verbs appear in the Old English corpus, and the forms marked with an asterisk are unattested reconstructions, formed by analogy.

In spite of heavy irregularities, there are four groups of similarly-conjugated verbs:

1. Āgan, durran, mōtan, and ƿitan
2. Cunnan, gemunan (outside the past tense), and unnan
3. Dugan, magan, and genugan
4. Sculan and þurfan

Note that the Old English meanings of many of the verbs are significantly different from that of the modern descendants; in fact, the verbs "can, may, must", and to a lesser extent "thurf, durr" appear to have chain shifted in meaning.

Anomalous verbs

Additionally, there is a further group of four verbs which are anomalous: "want" (modern "will"), "do", "go" and "be". These four have their own conjugation schemes which differ significantly from all the other classes of verb. This is not especially unusual: "want", "do", "go", and "be" are the most commonly used verbs in the language, and are very important to the meaning of the sentences in which they are used. Idiosyncratic patterns of inflection are much more common with important items of vocabulary than with rarely used ones.

Dōn 'to do' and gān 'to go' are conjugated alike; ƿillan 'to want' is similar outside of the present tense.

The verb 'to be' is actually composed of three different stems:

The present forms of ƿesan are almost never used. Therefore, ƿesan is used as the past, imperative, and present participle versions of sindon, and does not have a separate meaning. The bēon forms are usually used in reference to future actions. Only the present forms of bēon contrast with the present forms of sindon/ƿesan in that bēon tends to be used to refer to eternal or permanent truths, while sindon/ƿesan is used more commonly to refer to temporary or subjective facts. This semantic distinction (made only during the present tense) was lost as Old English developed into modern English, so that the modern verb 'to be' is a single verb which takes its present indicative forms from sindon, its past indicative forms from ƿesan, its present subjunctive forms from bēon, its past subjunctive forms from ƿesan, and its imperative and participle forms from bēon. (Modern German had an analogous, but even more complicated, development for its verb sein.) In late OE and ME, the form earon/earun, from the Old Norse erun, replaced bēoþ and sind (See also List of English words of Old Norse origin).

Strong nouns

Here are the strong declensional endings and examples for each gender:

For the '-u/–' forms above, the '-u' is used with a root consisting of a single short syllable or ending in a long syllable followed by a short syllable, while roots ending in a long syllable or two short syllables are not inflected. (A long syllable contains a long vowel or is followed by two consonants. Note also that there are some exceptions; for example, feminine nouns ending in -þu such as strengþu 'strength'.)

Note the syncope of the second e in engel when an ending follows. This syncope of the vowel in the second syllable occurs with two-syllable strong nouns, which have a long vowel in the first syllable and a second syllable consisting of a short vowel and single consonant (for example, engel, ƿuldor 'glory', and hēafod 'head'). However, this syncope is not always present, so forms such as engelas may be seen.

Weak nouns

Here are the weak declensional endings and examples for each gender:

Irregular strong nouns

In addition, masculine and neuter nouns whose main vowel is short æ and end with a single consonant change the vowel to a in the plural (a result of the phonological phenomenon known as Anglo-Frisian brightening):

Some masculine and neuter nouns end in -e in their base form. These drop the -e and add normal endings. Note that neuter nouns in -e always have -u in the plural, even with a long vowel:

Nouns ending in -h lose this when an ending is added, and lengthen the vowel in compensation (this can result in compression of the ending as well):

Nouns whose stem ends in -ƿ change this to -u or drop it in the nominative singular. (Note that this '-u/–' distinction depends on syllable weight, as for strong nouns, above.)

A few nouns follow the -u declension, with an entirely different set of endings. The following examples are both masculine, although feminines also exist, with the same endings (for example duru 'door' and hand 'hand'). Note that the '-u/–' distinction in the singular depends on syllable weight, as for strong nouns, above.

Mutating strong nouns

There are also some nouns of the consonant declension, which show i-umlaut in some forms.

Other such nouns include (with singular and plural nominative forms given):

Masculine: tōþ, tēþ 'tooth'; mann, menn 'man'; frēond, frīend 'friend'; fēond, fīend 'enemy' (cf. 'fiend')

Feminine: studu, styde 'post' (cf. 'stud'); hnitu, hnite 'nit'; āc, ǣc 'oak'; gāt, gǣt 'goat'; brōc, brēc 'leg covering' (cf. 'breeches'); gōs, gēs 'goose'; burg, byrg 'city' (cf. 'borough', '-bury' and German cities in -burg); dung, dyng 'prison' (cf. 'dungeon' by way of French and Frankish); turf, tyrf 'turf'; grūt, grȳt 'meal' (cf. 'grout'); lūs, lȳs 'louse'; mūs, mȳs 'mouse'; neaht, niht 'night' Feminine with loss of -h in some forms: furh, fyrh 'furrow' or 'fir'; sulh, sylh 'plough'; þrūh, þrȳh 'trough'; ƿlōh, ƿlēh 'fringe'. Feminine with compression of endings: cū, cȳ 'cow' (cf. dialectal plural 'kine')

Neuter: In addition, scrūd 'clothing, garment' has the umlauted dative-singular form scrȳd.

Nouns of relationship

Neuter nouns with -r- in the plural

Other such nouns: ǣg, ǣgru egg (ancestor of the archaic or dialectical form ey, plural eyren; the form egg is a borrowing from Old Norse); bread, breadru 'crumb'; cealf, cealfru 'calf'; cild 'child' has either the normal plural cild or cildru (cf. 'children', with -en from the weak nouns); hǣmed, hǣmedru 'cohabitation'; speld, speldru 'torch'.

Questions

Because of its similarity with Old Norse, it is believed that most of the time the word order of Old English changed when asking a question, from SVO to VSO. While many purport that Old English had free word order, this is not quite true, as there were conventions for the positioning of subject, object and verb in clause.

"I am..." becomes "Am I..."

"Ic eom..." becomes "Eom ic..."
