Questions & Answers about Ona ubiera się wolniej, ale wygląda dobrze.
The verb ubierać się is reflexive and literally means “to dress oneself / to get dressed.”
- ubierać = to dress (someone/something)
- się = reflexive particle (oneself)
So:
- Ona ubiera dziecko. – She dresses the child.
- Ona ubiera się. – She gets dressed (she dresses herself).
Without się, you would usually be talking about dressing another person or object, not yourself.
They all relate to clothing, but they focus on different actions:
ubierać się – to get dressed (the whole process)
- Ona ubiera się wolniej. – She gets dressed more slowly.
zakładać (clothes, shoes, etc.) – to put on a specific item
- Zakładam kurtkę. – I’m putting on a jacket.
nosić – to wear (in general, habitually)
- Ona nosi sukienki. – She wears dresses (in general).
In your sentence, we’re talking about the process of getting dressed, so ubiera się is the natural choice.
