Etymology
the word quantize is a modern scientific formation, built upon the latin root 'quantus', meaning 'how much'. this root is the source of the english word 'quantity'. the suffix '-ize', used to form verbs meaning 'to make or become', is of ancient greek origin. the term emerged in early 20th-century physics to describe the process of constraining a physical property, such as energy, to specific discrete units or 'quanta', as proposed by quantum theory. thus, the literal construction 'to make into quantities' elegantly captures the action of forcing a continuous system into a set of distinct, countable steps.
Analysis
quant is from latin 'quantus', meaning 'how much, how great'. ize is a verb-forming suffix from greek '-izein', via latin '-izare'.
