As an alternative rendering of the fourth term patibhāna Bhikkhu Ñānamoli proposes: perspicuity in expression and knowledge. 3 'The knowledge of the language concerning those things' means: the language corresponding to reality, and the unfailing mode of expression concerning the true meaning and the law.
