um … zu and damit
Express purpose with the same or different subject.
The rule
Use um … zu when the purpose has the same understood actor. Damit has its own subject and a final conjugated verb; it also works when actors differ.
same subject: um … zu · different subject: damit + final verb
Compare the subjects of action and purpose before choosing the connector.
um opens the purpose phrase and zu marks the final infinitive.
damit introduces a subordinate clause with its own subject and final finite verb.
