Why is the past of a modal verb not built with the Perfekt?
I was able to / I couldn’t.
In a sentence with a modal verb, the main verb always goes to the very end, conjugated.

-
ich and er are identical
With a modal verb, the first and third person singular take no ending — there is no ich kanne. In the plural the stem vowel returns to its original form.
ich kann · er kann · wir können
-
The infinitive waits at the very end
The conjugated modal stands in second position, the main verb goes to the end of the sentence as an infinitive. Whatever is in between stays between the two, and no zu follows a modal verb.
Ich muss heute früh aufstehen.
-
The past is spoken in the Präteritum
Modal verbs have a Perfekt form on paper, but nobody builds it in everyday speech. The Umlaut drops, -te is added.
ich musste · ich konnte · ich wollte
Commonly mixed up
Where a direct translation breaks. The hard questions come from here.
-
Ich kanne Deutsch.
Ich kann Deutsch.
Regular-verb habit: adding -e like ich mache. With a modal verb, ich stays bare.
-
Du musst nicht kommen. = “You’re forbidden to come”
Du darfst nicht kommen. = “You’re forbidden to come”
nicht müssen is freedom, not a ban. The one that states a ban is nicht dürfen.
-
Ich muss zu arbeiten.
Ich muss arbeiten.
The English habit of “have to work” makes people add zu. After a modal verb the infinitive is bare.
-
Ich habe nicht kommen gekonnt.
Ich konnte nicht kommen.
Not grammatically wrong, but nobody talks like this. The past of a modal is the Präteritum.
