The present tense of verbs with stems ending in "-t"
The same principle is true for verbs whose stem ends in "-t", such as "warten" (= to wait), "lauten" (= to be) and "antworten" (= to answer). These verbs also add an extra "-e-" before the normal verb endings in the "du", "ihr" and "er/sie/es" forms of the present tense.
The present tenses of the other aforementioned "-t-" verbs would give us the following examples:
Die Nummer lautet: 28 50 67.
(The number is 285067.)
Ihr antwortet nicht!
(You're not answering me!) The irregular verb "sprechen"
We have also come across a further verb which has an irregular present tense. The verb "sprechen" (= to speak) changes the stem vowel from "-e-" to "-i-" in the "du" and "er/sie/es" forms of the present tense.
