Why not simply use something like this:
static const char *voc[] = {
"bad|new",
"good|old",
};
Then...

Besides that, there are again some things that I've already mentioned
and that can be applied here, too, for example, not capitalizing
TERM_GOOD and TERM_BAD, the goto fail simplification, the terms memory leak.
