The Origin of Tacet or Tacit

Both words come from Latin, which explains why they look alike.

• Tacet comes from Latin tacere, meaning “to be silent.”
  It entered English through musical notation and stayed there.
• Tacit comes from Latin tacitus, meaning “silent” or “unspoken.”
  Over time, English writers used it to describe ideas or agreements not said out loud.

The spelling difference exists because English borrowed the words for different purposes. One stayed technical (music). The other became general and abstract.
