knowledge-based

The compound adjective 'knowledge-based' is a modern formation, reflecting the late 20th-century conceptualization of economies and systems. Its first element, 'knowledge', traces back to the Old English verb 'cnāwan' (to know, perceive), a Germanic word with deep Proto-Indo-European roots in ǵneh₃- (to know). The second element, 'based', originates from the Greek 'basis', via Latin and French, carrying the core idea of a foundation or support upon which something stands. The literal combination, "having knowledge as its foundation," directly informs its modern abstract meaning, describing entities—from industries to decision-making processes—whose core value and operation are fundamentally dependent on information and expertise rather than raw materials or physical labor.

Structure: knowledge (noun) + based (adjective suffix) knowledge: From Middle English 'knowleche', from Old English 'cnāwlǣc' (acknowledgment, confession), itself from 'cnāwan' (to know) + the suffix '-lǣc' (denoting action or practice). Its functional role is as the core noun element meaning "information, understanding, or awareness." based: From the past participle of the verb 'base', from Old French 'baser' (to found, build), from Latin 'basis' (foundation, pedestal), from Greek 'basis' (a stepping, a step). Its functional role is as an adjectival suffix meaning "having as a foundation or principal element."
