paradigm (n)

Very commonly “paradigm shift” or “paradigmatically.”

The OED provides us many definitions, for example:

“A conceptual or methodological model underlying the theories and practices of a science or discipline at a particular time; (hence) a generally accepted world view.”

and

“paradigm shift n. a conceptual or methodological change in the theory or practice of a particular science or discipline; (in extended sense) a major change in technology, outlook, etc.”

which are more or less reflective of the many pretentious and obfuscating ways this word has been employed in academic writing, but for almost all purpose, one should best understand this word as a fancy synonym for

“pattern.”
