This is the traditional pizza recipe in my family.
canonical requires a wider authoritative standard, not a personal or family tradition.

Synonym discussion

Sense: adjective/2

These four words all describe works of high standing, but with different emphases. Canonical stresses that experts agree a work belongs in a recognised set of essential texts — like the Western literary canon or the film studies canon. Classic is broader and more informal: a classic novel, film, or design is simply one of lasting quality, regardless of whether it appears on an official syllabus. Authoritative points to reliability and trustworthiness — an authoritative biography is one you can cite with confidence, but it may not be canonical. Seminal highlights influence: a seminal paper in biology changed how research is done in that field. For example, Shakespeare's Hamlet is both canonical and classic; Orwell's 1984 is canonical in many curricula; Watson and Crick's DNA paper is seminal in molecular biology; and the MLA Handbook is authoritative for citation style.

Etymology

GreekLatinFrenchEnglish

Canonical comes from the Latin word canonicus, meaning 'according to a rule,' which in turn comes from the Greek kanon (κάνων), meaning 'measuring rod' or 'standard.' The Greek kanon was originally a literal rod used by builders to ensure straight lines, and over time its meaning shifted toward any rule or standard by which things are measured. The word entered English via Church Latin, where canon referred to the official list of books accepted into the Bible — hence, canonical writings were those that met the Church's rule or standard. From there, the meaning broadened to include any work, practice, or form that is accepted as the authoritative standard.
