An inability to speak.
Muteness mentioned in Star Trek:
-In the TOS episode "The Empath", McCoy determines that Gem does not have any vocal cords, not even vestigial, indicating that she comes from a species of mutes. Kirk observes that she is like the naturally mute people of the civilization on Gamma Vertis IV.
-In the TNG episode "Loud as a Whisper," the deaf-mute mediator Riva was a member of the ruling family on Ramatis, all of whom shared a genetic condition that rendered them deaf.
- In the DS9 episode "Progress" The two Bajoran farmers Baltrim and Keena were rendered mute during the Cardassian Occupation of Bajor.
