German verb conjugation is largely regular, but one specific feature — separable prefix verbs — is frequently cited as one of the trickiest things for learners to get used to.
Many German verbs are built from a base verb plus a prefix that changes its meaning — aufstehen ("to get up") comes from stehen ("to stand") plus auf. In a normal present-tense sentence, that prefix detaches and moves to the very end of the clause: "Ich stehe auf" ("I get up," literally "I stand up," with "up" pushed to the end). The verb and its prefix are still one grammatical unit — they're just not written together in that sentence position.
Because the prefix at the end of a sentence can completely change a verb's meaning, you sometimes need to hear or read the whole sentence before knowing exactly what verb is actually being used — a real parsing challenge distinct from vocabulary difficulty itself.
Aside from the separable-prefix behavior, German verb conjugation across persons and regular tenses follows consistent, learnable ending patterns, with a manageable set of irregular high-frequency verbs (similar in spirit to English's irregular verb cluster).

They're expected to be, given how frequently they appear in everyday German sentences.
