For Example: ex-ample.com
Isn't that the punch line of a joke? Or eight different jokes? Site for people who have lost weight and want to keep it off, obviously. No relation to exam-ple.com which deals in test-preparation material, or ex-amp-le.com which has something to do with electricity.
Seriously: Get lots of different people (in real life, not here) to look at your proposed site names with the hyphens in different places. Make sure it can't be reanalyzed in any unintended way.
