Irregular Verbs in Old English
Old English has a handful of verbs that don't follow the normal strong or weak conjugation patterns. Instead, they form their tenses in unpredictable ways that you simply have to memorize. The most common ones — bēon (to be), gān (to go), dōn (to do), and willan (to wish/will) — show up constantly in Old English texts, so learning their forms pays off quickly.
Common Irregular Verbs
Bēon/wesan (to be) is the most irregular verb in Old English, just as "to be" is in Modern English. It actually draws from two different roots (bēon and wesan), which is why its forms look so different from each other.
- Present: eom (I am), eart (you are), is (he/she/it is), sind(on) (we/you/they are)
- Past: wæs (I/he/she/it was), wǣre (you were), wǣron (we/you/they were)
Gān (to go) uses a completely different stem in the past tense — a pattern called suppletion (the same reason we say "go/went" in Modern English).
- Present: gā (I go), gǣst (you go), gǣþ (he/she/it goes), gāþ (we/you/they go)
- Past: ēode (I/he/she/it went), ēodest (you went), ēodon (we/you/they went)
Dōn (to do) mixes features of both regular and irregular conjugation. Notice the vowel shift between present and past.
- Present: dō (I do), dēst (you do), dēþ (he/she/it does), dōþ (we/you/they do)
- Past: dyde (I/he/she/it did), dydest (you did), dydon (we/you/they did)
Willan (to wish, will) expresses intention or futurity. Its past tense, wolde, is the ancestor of Modern English "would."
- Present: wille (I will), wilt (you will), wile (he/she/it will), willaþ (we/you/they will)
- Past: wolde (I/he/she/it would), woldest (you would), woldon (we/you/they would)
Tips for Translation
Because these verbs are so common, you'll encounter them in nearly every Old English passage. A few things to keep in mind:
- These verbs don't follow strong or weak patterns, so trying to apply ablaut series or dental suffixes won't work. Memorize them as individual sets.
- Bēon and wesan can both mean "to be," but bēon often carries a habitual or future sense (bið = "will be" or "is always"), while wesan tends toward simple present or past statements.
- Context determines whether willan means "to wish" or "will (future)." In many Old English sentences, it still carries a sense of desire rather than pure futurity.
Preterite-Present Verbs
Preterite-present verbs are a small but important class of verbs whose present tense forms historically come from the past (preterite) tense of old strong verbs. Over time, speakers started using those past-tense forms with present-tense meaning, and then built new past tenses on top of them using weak verb endings. The result is a group of verbs where the present tense looks like a strong past tense, and the actual past tense looks like a weak verb.
This matters for translation because if you don't recognize a preterite-present verb, you might mistake its present tense for a past tense.
How They Work
Here's the core pattern:
- The present tense uses forms that resemble strong verb preterites (with ablaut vowel changes and no personal endings in 1st/3rd person singular).
- The past tense was formed later using a weak dental suffix (-de, -te), much like regular weak verbs.
- The past tense often carries subjunctive or conditional meaning ("would," "might," "could").
For example, take witan (to know):
- Present: ic wāt (I know) — wāt looks like a strong past tense form, but it means present "I know"
- Past: ic wiste (I knew / I would know) — formed with a weak dental suffix
Common Preterite-Present Verbs
| Verb | Meaning | Present 1sg | Past 1sg |
|---|---|---|---|
| witan | to know | wāt | wiste |
| cunnan | to know, be able | cann | cūðe |
| sculan | shall, must | sceal | scolde |
| magan | may, be able | mæg | meahte / mihte |
| mōtan | must, may, be allowed | mōt | mōste |
Notice that cūðe is the ancestor of Modern English "could," scolde became "should," and mihte became "might." These verbs are the direct source of our modern modal verbs.
Why This Matters for Translation
- When you see ic cann, don't translate it as "I could" (past). It means "I know" or "I am able" (present).
- When you see ic cūðe, it can mean "I knew" or "I would be able to," depending on context. Watch for subjunctive or conditional constructions.
- The preterite-present verbs sculan, magan, and mōtan frequently appear with infinitives, just like modern modals: ic sceal gān = "I must go."
Recognizing these verbs on sight is one of the most useful skills for reading Old English fluently. Their forms are few and they appear often, so the memorization effort is well worth it.
