Learn Swedish: Nybörjaren hade en urdålig rutin. - The beginner had a terrible routine.

The prefix ur- acts as a strong intensifier. While dålig means bad, adding ur- turns it into extremely bad or terrible. It is one of several common prefixes, like jätte- or tok-, used in everyday Swedish to heavily crank up the degree of an adjective.

Does ur- always act as an intensifier, and can I attach it to any adjective?

As an adjective intensifier, ur- means extremely and is highly productive, meaning you can attach it to most common adjectives to create words like urbra (extremely good) or urkul (extremely fun). However, be aware that when attached to nouns, ur- often carries its original historical meaning of ancient or original, such as in urskog (primeval forest). In this sentence, it functions purely to intensify the adjective dålig.
