Hermeneutics is the theory of text interpretation, especially philosophical and religious texts and wisdom literature. The terms "hermeneutics" and "exegesis" are sometimes used interchangeably. Hermeneutics is a wider discipline that includes written, verbal, and nonverbal communication. Exegesis focuses primarily upon texts.
Hermeneutics is what Lojbanists have been doing for a long time. Instead of creating new words with meanings they can explain, Lojbanists have been involved in the activity of trying to decipher either broken definitions of gismu and cmavo or those written by unreachable people.
