There were several years between the time I first learned the word segue, and the first time I saw it spelled. I did, however, know at the time what a Segway was. So, for years until I encountered it in writing, my adolescent little ESL brain assumed they were the same word. I used to imagine a tiny guy driving a Segway from one topic to the next, and I honestly believed this was what the word meant. Segwaying into the next topic.
