Are there Male/Female equivalents for every name?

Probably not. Consider that some names are ambiguous: Chris, Pat (SNL routine) so the M/F are the same.

Christopher/Christine Patricia/Patrick
The nicknames are the same but the names aren’t.

That’s assuming someone is given the name “Christopher” or “Christine” but if a parent names a kid “Chris” then “Chris” is the kids name, so “Chris” is a name without M/F equivalent.

There are probably not equivalents for every name, but I bet you can find a lot of them in baby name books/internet lists.

There are a lot of wacky names out there. I knew a girl once named “Destiny.” Or how about old-fashioned girl names like “Chastity” or “Prudence”? It’s hard to think of male equivalents to those.

male equivalent of “Chastity” is “Player”
male equivalent of “Prudence” is “Gambler”
and…male equivalent of “Destiny” is “Doomed.”

@christybird—there’s also the Matrix character: Trinity. :-)
