What does dastardliness mean?
Dastardliness denotes contemptible cowardice — the kind of fearful, dishonourable behaviour that provokes disgust rather than mere pity. The noun derives from 'dastard', a Middle English word for a base coward, itself built with the '-ard' suffix long associated with pejorative character types. Unlike ordinary shyness or caution, dastardliness implies a moral failing: acting in a mean, sneaky, or treacherous manner because one lacks the nerve to face matters openly. The word appears most often in formal registers — political rhetoric, editorial commentary, military and historical writing — where speakers seek a weighty, damning label for shameful conduct, such as attacking the defenceless or betraying an ally. Its force lies in combining two accusations at once: cowardice and baseness. Though uncommon in everyday conversation, it remains a vivid choice for writers who want to condemn an action as not just fearful, but disgracefully so.
nounThe quality of being a dastard; despicable, contemptible cowardice, especially as shown in shameful or treacherous behaviour.
- Contemptible, disgraceful cowardice; the trait of behaving in a mean or treacherous way out of fear.
"The general condemned the dastardliness of an attack launched on unarmed civilians."
"Historians still debate whether the commander's retreat was prudent strategy or sheer dastardliness."
"He denounced the sabotage as an act of pure dastardliness, unworthy of any honourable opponent."
Dastardliness is an abstract mass noun and does not normally take a plural; treat it as singular and uncountable in all standard usage.
"Such dastardliness has rarely been seen in the annals of naval warfare."
The word 'dastard' hides an old insult in plain sight: the '-ard' ending that brands someone a coward is the same one that gave us 'drunkard' and 'lizard' — a medieval shorthand for a fool of a particular flavour.

Etymology of dastardliness
Dastardliness comes from 'dastard', attested in Middle English by the mid-15th century, which combines 'dast' — an old form meaning stunned or daunted, akin to modern 'daze' — with the '-ard' suffix used in medieval English for contemptible types, as in 'drunkard'. The abstract noun 'dastardliness', denoting the quality of such cowardice, developed later from the adjective 'dastardly'. Its Germanic root connects it etymologically to 'daze' and 'dazzle'.

Dastardliness is a relatively rare, strongly condemnatory term used almost exclusively in formal or rhetorical contexts — speeches, editorial writing, historical and literary prose. It carries moral judgement rather than neutral description: to call something dastardliness is to brand it shameful, not merely timid. It is an abstract mass noun and has no ordinary plural.
