behavioural
UK: bɪˈheɪvjərəl | US: bɪˈheɪvjərəl
adj. relating to or involving behavior
adj. (psychology/sociology) pertaining to observable actions or responses
The word "behavioural" stems from the verb "behave" (Middle English behaven, from be- + haven, meaning "to hold or conduct oneself"). The suffix "-iour" (variant of "-ior") was added to form the noun "behaviour," denoting manner of conduct. Finally, "-al" (Latin-derived adjective suffix) transforms it into an adjective describing qualities related to behavior. The evolution reflects a logical shift from action ("behave") to abstract noun ("behaviour") to descriptive term ("behavioural").
