Irregular English verbs: origins, patterns, and top 20

Be, was, were. Go, went, gone. Sing, sang, sung. These forms seem to come out of nowhere when you start. In reality, they perpetuate very old mechanisms of English, and you can tame them by grouping them by sound pattern.

Why these verbs exist

English inherits an ancient Germanic system where two major families coexisted. The so-called strong verbs changed vowel to mark tense (a phenomenon of "ablaut"), hence series like sing, sang, sung. The so-called weak verbs added a dental suffix, which has become -ed today (work, worked). Many less common verbs have been regularized, but the most common have retained their irregular forms, which explains their persistence in usage.according to Cambridge Grammar.

Some cases are even more particular. Go uses a preterite derived from another historical verb (wend) to give went, a classic example of "suppletion" well attested in etymology.according to Etymonline. Be accumulates several ancient roots, hence was, were, and been. This is not chaos; it is history frozen in grammar.

The major patterns that help

Grouping verbs by patterns makes memorization lighter. Here are the baskets that come up most often, with 3 forms in the order base, past, past participle.

• i-a-u change: sing, sang, sung; drink, drank, drunk; ring, rang, rung; begin, began, begun; swim, swam, swum.
• i-o-i pattern with participle in -en/-en: write, wrote, written; ride, rode, ridden; drive, drove, driven.
• Past in -o and participle in -en: speak, spoke, spoken; break, broke, broken; choose, chose, chosen; steal, stole, stolen; wake, woke, woken.
• Past and participle in -t/-d: keep, kept, kept; feel, felt, felt; leave, left, left; build, built, built; say, said, said; pay, paid, paid; tell, told, told.
• No variation: put, put, put; cut, cut, cut; set, set, set; hit, hit, hit; let, let, let; cost, cost, cost.
• Suppletion and isolated cases: go, went, gone; be, was/were, been; do, did, done.

Common pitfalls

• Participle vs past: I have gone (not I have went). I have seen (not I seen). I have done (not I did in a perfect).
• Regional doublets: learned / learnt, dreamed / dreamt, burned / burnt. Both exist; the -t variant is more common in British English, while -ed is more widespread in American.
• get in the participle: got in common British English, gotten very frequent in American (I have gotten better).
• be in the preterite: was in singular, were in plural. And subjunctive: if I were is the standard careful form.
• show: past showed, participle often shown. Sometimes showed is heard as a participle, but shown remains the careful reference.

My experience

At first, I confused everything. Then I stopped seeing a "list of exceptions" and I placed each verb into a sound basket. i-a-u was my favorite: I recited sing, sang, sung; drink, drank, drunk in rhythm while walking. I also wrote triads on post-its, stuck near the kettle. The next day, I moved on to the pattern write, wrote, written; ride, rode, ridden, which I hummed to a silly melody. Nothing complicated, just short but regular repetitions, with the ear as a guide. When a verb deviated, I noted the reason (went comes from wend) to anchor it with a little story.

How to train yourself

Work by patterns and by ear. Recite the three forms out loud, link them into mini-phrases, then mix two similar verbs to check that your brain is keeping up. If you want to practice in a targeted way, the Conjugation module of Discus lets you choose tenses to review; the app then randomly picks from your selection. You can open it here: Conjugation.

In essence, English irregular verbs are not a wall, but families of sounds. Once the patterns are in place, the rest becomes a matter of checking details: participle in -en here, -t there, and two or three tellable cases like went. And that is within the reach of any motivated learner.
