What does canonically mean?
"Canonically" is a formal adverb meaning "in accordance with a canon" — an officially recognized body of rules, texts, or standards. Its oldest sense belongs to religion: a book, practice, or doctrine is treated canonically when it conforms to authoritative scripture or church law, as when scholars discuss which Gospels are canonically accepted. In the twentieth century the word acquired a second life in mathematics, logic, and computer science, where something done canonically follows the natural or uniquely determined way of representing an object — for example, sorting data into its canonical order. The adverb carries connotations of authority, orthodoxy, and precision, and it appears almost exclusively in academic, theological, and technical prose rather than everyday conversation. It derives from the Greek kanōn, a measuring rod or rule, which passed through Latin into English as "canon." Knowing "canonically" helps readers navigate discussions of sacred texts, literary canons, and standardized technical representations alike.

"Unicode defines a canonically equivalent form for strings that differ only in accent marks."
The word 'canon' began as a Greek measuring rod — so 'canonically' is literally what happens when you measure ideas against the official ruler.

Etymology of canonically
Canonically derives from the Greek kanōn (κανών), meaning a rod, rule, or standard of measurement, which entered Latin as canon and then Old French before reaching English in medieval times. The adjective "canonical" developed from this noun, and the adverb "canonically" was formed from it by the usual addition of -ly, becoming established in English usage several centuries ago alongside scholarly and ecclesiastical discourse. Cognates include "canon," "canonical," and, more distantly, words like "cannon" (originally a tube or rule-shaped object).
