What is the difference between a regular verb and an irregular verb?

Answer 1

In English,strong, or irregular verbs form their past tenses by means of ablaut, that is a change in the stem vowel. They are among the oldest and commonest of English verbs. For example take:took; come:came; see:saw; write:wrote, and so on. The verbs to go and to be even have a different stem - or two!- in the past tenses.

Weak, or regular verbs form their past tenses by the addition of the suffix, -d, -ed or -t, without changing the stem vowel. For example ask:asked; donate:donated; learn; learned or learnt. Some otherwise regular verbs may distinguish between the active and the passive past participle, for example proved:proven and mowed:mown

Newly coined verbs are weak, and it may seem that the productive period of strong verbs is over, but the English speaker's affinity for the older, strong forms is still in operation, as seen in popular usages like dive:dove and sneak:snuck, where the "correct" past forms are dived and sneaked, respectively.

Answer 2

In English, in the present tense, most verbs are regular. For example you say, "I walk" and "He walks" so the third-person singular form of the verb is created simply by adding an s. Additionally, there are regular verbs such as wash or box that take 'es' and are considered regular. Generally speaking, one normally adds an 's' to a verb or an 'es' if the verb ends in ch, sh, x, or s (e.g., matches, washes, boxes, dresses). Has, does, and goes are the most-common irregular verbs in the present tense (not haves, dos, or gos).

In the past tense regular verbs form the simple past by adding an "ed" ending (or just d if the verb already ends in an e). It may be necessary to double the final consonant, change the y to ie, or add a k to ensure the sound remains the desired one (e.g., stop->stopped, study->studied, panic->panicked), but these verbs are still classified as regular. Irregular verbs are those that do not follow these rules (e.g., win->won, stand->stood, go->went, put->put).
