What does casualness mean?
Casualness is the quality of being casual — relaxed, informal, and free from stiffness or ceremony. It describes everything from a way of dressing to a manner of speaking, an atmosphere in a room, or an attitude toward responsibility. In its most favourable sense, casualness suggests comfort and effortlessness: a host's casualness puts guests at ease, and a writer's casualness makes difficult ideas feel approachable. But the word can also shade into criticism. When applied to how someone treats duties, rules, or other people's feelings, casualness implies a troubling lack of care or gravity — 'the casualness with which he broke his promises' is rarely meant as praise. The word derives from 'casual', which traces back through French to Latin 'casus' (fall, chance), so at its root casualness carries the idea of acting as things happen, by chance rather than by design. It is an uncountable noun, common in both British and American English.
The quality or state of being casual; a relaxed, informal manner, style, or atmosphere.

Uncountable.
An unconcerned or insufficiently serious attitude towards something, often implying a lack of due care or respect.
"The auditor noted the casualness with which expenses had been recorded."

Casualness is one of those rare words that can be either the highest compliment — effortless ease — or the sharpest criticism: an off-putting lack of care.

Etymology of casualness
Casualness is formed from the adjective 'casual' plus the noun-forming suffix '-ness'. 'Casual' entered English in the late 14th century via Old French from Late Latin 'casualis', derived from Latin 'casus', meaning 'fall' or 'chance event' — the same root that gives us 'case', 'occasion', 'accident' (via its sense of something that happens), and 'cadence'. The original sense of 'casual' related to what happens by chance; the modern sense of relaxed and unplanned informality developed later, and 'casualness' followed as its abstract noun.

Casualness is largely neutral to positive when describing dress, style, or atmosphere ('the casualness of the café'), but it can carry a negative connotation when describing attitude or behaviour, implying insufficient seriousness or care ('the casualness of their apology'). It is a moderately formal abstract noun, more common in written than spoken English.
