A variant spelling or regional term, possibly related to book-keeping, traditional knowledge, or a specific cultural practice (exact meaning uncertain).
The etymology is unclear; it might be a variant of 'book,' a term from another language, or a specialized jargon term. Without clear documentation, the origin remains uncertain.
Words like 'bukh' remind us that language is constantly evolving and that old dictionaries capture terms on the verge of extinction. Sometimes a single word is our only evidence that a practice or thing once mattered to people.
