In English, verbs take no endings, but German has more endings for verbs in the past tense than English. Note that in German, the present perfect tense is mostly used for the spoken language.
In German, verbs in the present perfect tense are formed either regularly or irregularly (similar pattern in English).
The present perfect tense is constructed by using the present tense of “haben” + the past participle of the main verb. The passt participle is formed by using the stem of the verb and you add “ge-” in front and “-t” at the end of the stem. The stem is the form of the infinitive without -en or -n.
Example:
Infinitive: lernen
Stem: lern
Past Participle: gelernt
haben | |
The present perfect tense is constructed by using the present tense of “haben” + the past participle of the main verb. The passt participle is formed by using the stem of the verb and you add “ge-” in front and “-et” at the end of the stem (ends in -d or -t need an extra -e):
Example:
Infinitive: reden
Stem: red
Past Participle: geredet
Word order:
The form of “haben” takes the second position in a sentence, while the past participle goes to the end of the sentence or clause.
Note:
Verbs of motion or verbs which express a change (of state) form the present perfect with a form of sein plus the past participle.
sein | |
Example:
Person: Ich
Infinitive: lernen
Stem: lern
Past Participle: gelernt
Tense: Ich habe gelernt.
Example:
Person: Ich
Infinitive: reisen (motion -> form of “sein)
Stem: reis
Past Participle: gereist
Tense: Ich bin gereist.
There are a lot of irregular formations of the present perfect (to much for one page), but most German dictionaries have a list of irregular verbs in which the past participles are given.
