The Past Tense: Perfekt
The Past Tense: Perfekt
Spoken German almost always uses a compound past tense — haben or sein plus a past participle pushed to the end of the clause. English has a similar-looking compound tense, but German splits it apart in ways English never does.

A two-part verb, split across the clause
Ich habe gestern Pizza gegessen. (habe stays in position 2, gegessen goes to the very end)
I ate pizza yesterday. (a single past-tense verb, kept together)
German's everyday past tense is a compound: a helper verb (haben or sein) takes the normal 'verb-second' position, while the past participle (gegessen) is pushed all the way to the end of the clause. English has a similar-looking compound ('I have eaten') but never splits it apart — the auxiliary and participle stay glued together right after the subject. In German, everything else in the sentence (gestern, Pizza) crowds into the middle, between habe and gegessen. This is the same 'verb bookends' pattern you saw with modal verbs, and it's one of the first places English speakers default to English word order by habit.
Choosing haben vs. sein
Ich habe gegessen (most verbs) vs. Ich bin gegangen (motion / change of state)
I have eaten vs. I have gone — English always uses 'have' for the perfect
English's perfect tense always uses 'have' (I have eaten, I have gone, I have become) — there's no verb-by-verb split. German divides its helper verb: most verbs use haben, but a specific class — verbs of motion (gehen 'go', fahren 'drive', kommen 'come') and change of state (werden 'become', aufwachen 'wake up', sterben 'die'), plus sein and bleiben themselves — use sein instead. There's no way to derive this from English, since English doesn't make the distinction at all; it has to be learned per verb, though 'does it involve moving from A to B, or changing state, with no direct object?' is a decent rule of thumb.
Participle formation: weak vs. strong verbs
gemacht (weak: ge- + stem + -t) vs. gegessen (strong: ge- + changed stem + -en)
made vs. eaten — English also has regular (-ed) and irregular past participles
Just as English has regular verbs (walk → walked) and irregular ones (eat → eaten, go → gone), German splits into 'weak' verbs, which form the participle predictably with ge-...-t (machen → gemacht, spielen → gespielt), and 'strong' verbs, which often change their vowel and end in -en (essen → gegessen, trinken → getrunken, sehen → gesehen). Strong verb participles must be memorized individually, the same way you memorized English's irregular verb list.
