Marvel tends to use hyphens or spaces (Spider-Man, Ant-Man, Iron Man) while DC usually does compound words (Superman, Batman, Aquaman, although Wonder Woman). I could find no compound wordman superheroes in the lists of Marvel superheroes I found, but there are some -man and (space)man characters in the DC list.
