    Irregular Verbs

    In English and in German, there are different kinds of verbs. What constitutes an irregular verb is if there are conjugation changes in either the simple present tense (das Präsens), or the the simple past (das Präteritum/Imperfekt), that differ from the regular conjugation patterns. Verbs that show now changes in their conjugation in any of the tenses are called "regular verbs". Verbs that have irregularities in their conjugation in any or all of the tenses is considered an "irregular verb". 

    1. Regular verbs

    To demonstrate this, let's first look at a verb that shows no irregularities in its conjugation. This means that the word stem stays the same for all pronouns and all tenses. (Example: spielen - to play)

    Notice that the verb stem "spiel-" stays the same for all pronouns and all tenses. 

    2. Irregular Verbs 

    A number of verbs in the present tense second- and third-person singular forms (“du” and “er/sie/es”) have a stem vowel change. Some verbs substitute “i” for “e” (e.g. treffen). Other substitutions include “ä” for “a” (laufen, fahren, waschen) and “ie” for “e” (lesen, sehen, empfehlen). Some irregular verbs show now changes in the present tense conjugation, but in the simple past conjugation (e.g. gehen)

    Notice how in the example above, the vowel change appears for "du" and "er/sie/es". The word stem is also different in the simple past conjugation.
    The verb "sein" (to be), and "haben" (to have) are both irregular verbs, as they follow an irregular conjugation pattern.
