English verbs, except Modal, have three forms. The forms help express thought about Time (PRESENT, PAST or FUTURE) and Aspect (Simple, Progressive, Perfect, or Perfect Progressive).

The first form can make the Present Simple:
I write.

The second form can make the Past Simple:
I wrote.

The third form can make the Perfect:
I have written (Present);
I had written (Past);
I will have written (Future).

The first form and the ending ING can help talk about activities we view as Progressive in character:
I am writing.

Regular verbs take the ending ED, in the second and third forms. Irregular verbs may take various shapes and show vowel patterns.

mean meant meant
read read read
<I:> <e:> <e:>

Outside English-speaking countries, these are mostly American English or British English that people learn for their Englishes. We may compare the two distinct language varieties here.

Some verbs are regular in American English, although they are irregular in British, and the other way round. When the verb can be regular and irregular in American, we list both the forms. When either regular or irregular form prevails in American, we can mark it as PREV.

Dependent on prevalence, we can mark forms that occur mostly in British English as BE. When the form is associated mostly with American English, we can mark it as AE.

Please note that literary American English may employ irregular verb forms for versatility, and stay with regular forms for everyday usage.

FIRST FORM SECOND FORM THIRD FORM
chide chided / chid chided / chid / chidden
gild gildedPREV / gilt gildedPREV / gilt
learn learned / learntBE learned / learntBE

Let us remember, the speech sound <L> happens to be an individualist in American English. Appendix 1 has more.

Most dictionaries list irregular verbs alphabetically. We list them looking to speech sound patterns. This can make remembering irregular forms easier. We might just read a few verbs at a time and begin to remember them. The phonetic transcription is generalized.

For clarity, the vowel chart below shows a generalized picture for high, mid, and low vowels in American English. Vowel height regards the position of the tongue in the mouth (high, mid, or low).

Please mind that American English is a live language and live languages change. Vowel charts and verb lists may not last forever.

VOWEL CHART, HIGH AND LOW VOWELS

The colon — <:> — marks the speech sounds we pronounce longer. Vowels often become a bit higher, when prolonged. Please compare “reed” <I:>, and “bid” <I>.

The symbol <ə> is for the shwa. It is a neutral vowel sound. We find it in unstressed syllables. If stressed, the shwa most often becomes a full vowel. Some transcriptions consider <Λ> a reduced speech sound, too. This is why the table presents it without the colon.

The <æ> joins <e> and <Λ> qualities.

We may star the second and third irregular forms that can be of same shapes, in American English. We do this to perceive, not to learn by rote.

To remember verb patterns, we may think about the place and manner we make speech sounds. The sounds <p> and <b>, or <v> and <f> differ in voicing solely; <l> and <r> share much in place, and differ in manner, similarly to <t>, <d>, <n>, and <s>. We can compare the verbs “to beat”, “to lean”, and “to leap”.
