When I was about six and first encountered the word 'slippers', I asked what it meant, and was told that slippers were shoes you put on your feet indoors. I made the assumption that they were called 'slippers' because you slide around on them indoors, like on ice skates, and was disappointed for a long time afterwards that this didn't seem to work.
