User vs usage friendly
In English usability folks typically talk about user friendliness. Literally translated, user friendly translates in Dutch to "Gebruikersvriendelijk". In Dutch "Gebruikersvriendelijk", however, is used interchangeably with “Gebruiksvriendelijk” (see also: Taaladvies) which translates literally back to “usage friendliness”. Not too fast: these might be two different concepts after all.

User friendly
User friendly is about being nice to the user. Making something user friendly may be about nice icons, nice words, nice visual design, but you can, strictly speaking, still be very friendly and not allow a user to accomplish a certain task.
