About the only Swedish word apart from smorgasbord and gravlax that has been assimilated into the English language that I know of. It simply means representative (in the sense that the ombudsman is a person representing others) and is an incredibly dull word that just reeks of order and regulations. I don't know if this somehow reflects the character of the Swedes; we tend to be a bit proud of our talent for rationality and bureaucracy in some perverse and/or masochistic way.
