Questions & Answers about Ich ziehe mir die Jacke über, weil es windig ist.
überziehen literally means “to pull over” or “to slip on” an outer garment on top of what you’re already wearing. It’s a separable verb: über is the prefix, ziehen the root.
By contrast, anziehen simply means “to put on” clothes in general. If you say Ich ziehe mir die Jacke an, you’re putting the jacket on from scratch. If you say Ich ziehe mir die Jacke über, it often implies you’re slipping it over your existing outfit (for example, over a sweater).
German has many “dative‑reflexive” dressing verbs of the form sich etwas (an/aus/über)ziehen. Here mir is a dative reflexive pronoun showing that the subject and the recipient of the jacket are the same person.
- It is technically optional: you can say Ich ziehe die Jacke über, and native speakers will understand you.
- Including mir is more idiomatic, because it emphasizes “I’m putting this on for myself.”
