Etymology

coherent = co<together> + her<stick> + ent<adjective suffix>

  • her (Latin haerere): "to stick, cling"
  • ent: adjective-forming suffix indicating a state or quality

Etymology Origin:
The word "coherent" originates from Latin cohaerere, meaning "to stick together." The prefix co- (together) combines with haerere (to stick), reflecting the idea of unity or logical connection. Over time, it evolved to describe clarity in thought, consistency in argument, and even the synchronization of waves in physics. The core concept of "sticking together" remains central to all its modern meanings.
