Using the table

The rows cover the six person/number patterns. Formal Sie uses the same verb form as plural sie, with its capital letter retained in a sentence. German Perfekt often translates naturally as an English simple past, so choose the meaning from context.

These are ordinary main-clause forms. A separable prefix stays joined with its verb in a verb-final subordinate clause. Modal verbs with another governed infinitive use the separate double-infinitive pattern rather than mechanically keeping the standalone perfect forms above.
