You keep using that word. I do not think it means what you think it means. ;)
Segue - This can be used as a verb or a noun. It means any smooth, uninterrupted transition from one thought or idea to another. There are many ways to insert a segue into one's speech.
You can use a segue to be illustrative (for example), contrasting (on the other hand), concessional (at least), comparative (likewise), consequential (as a result), and even conclusive (finally).
I personally like the obvious ones.
Example:
Did you see the picture of Darth Vader riding the segway? Speaking of scariest villains in the galaxy, I heard Donald Trump is delusional with the idea that he could run for president of the United States.
Segway - This is a noun. It's a two-wheeled motorized personal vehicle consisting of a platform for the feet mounted above an axle and an upright post surmounted by handles. (See picture above)
So why all the confusion? Well apparently the company responsible for creating the Segway trademarked the name because of its similarity to segue, on the notion of it being "a smooth transition from one place to another".
Thanks, guys.
