Relating to or concerning attitudes; involving or based on attitudes or the positioning of the body.
From attitude (from Italian attitudine, from Latin aptitude meaning 'fitness') + -al (adjective suffix). The word developed in modern English (19th-20th centuries) to describe things related to attitudes or postures.
Psychology borrowed 'attitudinal' to describe how our beliefs and body language are connected—slouching or standing tall literally changes our attitude, which researchers can measure. Your posture doesn't just reflect your mood; it can create it.
