I want to thank Jannis for his teapot riddles with this.
I am one word, but have 2 or more different meanings.
I’m two nouns and a verb,
Take my first, flip it around, you’ll get my last,
You could find anywhere, in tubes and pipes,
It’ll be quite a long time, for half of my life,
Follow me, I’ll show you the way to another place,
I’ll keep your dogs, cats, bunnies in line,
While I help detectives solve a crime
Connecting the dots, but more than that, Bringing your cable to your tv, Transporting power, that stuff’s easy
