The B'rknaa language served as the original tongue of the B'rknaa species originating from the planet Indobok. Characterized by its piercing, grating vocalizations, it notably lacked a first-person pronoun due to the B'rknaa's existence as a communal mind.
It is documented that the protocol droid C-3PO acquired proficiency in B'rknaa after Captain Jace Forno left him, albeit temporarily, on Indobok during the year 5.5 BBY.
