Comments: The oldest attested uses of the word (15th-16th c.) refer to jewels of great price. This, and the use of *-biči in aita-bitxi ‘godfather’, etc. (ama-bitxi, seme-bitxi, alab-itxi), match well with the NC meanings ‘rich’ and ‘honor(able)’. The ‘god-(parent, -child)’ usage is probably calqued on Romance forms like Fr. beaupère ‘godfather’. Palatal /č/ by expressive palatalization and/or position between two /i/s; the form pitxi by expressive devoicing.
