Easy to solve wall, some of the ansas need work maybe. TY

Is the number of exclamation marks a clue to the order you wrote the groups in ?

Soooo... not hidden measurements then?

I also forgot it was spelt Synonynonyms. My bad.

Thanks for setting. Pretty good (but very easy)- apart from the Reg group, you really want to try to find a better connection than just "names", even if you don't insist on it for the answer. Usually this means they're characters in a story or a show of some kind. Or... you replaces Reg with Sam then you get "names that make a word if you add E'. Still a bit weird but slightly more satisfying.

Short boys names is not really good enough! Also distance group didn't accept measurements.
