The word "fore-runners" refers to those who come before, precede or pave the way for others. Its antonyms include followers, successors, imitators, and copycats, who come after someone has established something new. They may lack the drive, initiative or innovation of their predecessors or may simply choose to follow in their footsteps rather than lead. Another antonym could be detractors or opponents, who resist or reject the ideas or actions of the fore-runners. Regardless of the antonym used, these words underscore the importance of those who lead the way and those who follow, and the dynamics that shape human progress and development.
