What does effectualness mean?
Effectualness is a formal noun meaning the quality of being effectual — that is, the capacity to produce the intended or desired result. It derives from 'effectual', itself rooted in the Latin efficere, 'to bring about or accomplish'. In practice, effectualness overlaps almost entirely with the much more common word effectiveness, but it retains a slightly more literary and old-fashioned flavor, appearing mostly in formal, legal, or official contexts where writers wish to stress that something actually accomplished its purpose rather than merely having the potential to do so. One might speak of the effectualness of a remedy, a policy, or an argument. Because it is rare in everyday conversation, it can sound stilted if used casually; in appropriate registers, however, it lends prose a precise, deliberate tone. Its negative counterpart, ineffectualness, describes the failure to achieve a desired outcome.

Effectualness does what it says on the tin — it's the noun form of 'effectual', a word that once meant simply 'that which produces an effect', and it outlived most of its rivals by refusing to die entirely.

Etymology of effectualness
Effectualness is formed from the adjective 'effectual' plus the noun-forming suffix '-ness'. 'Effectual' entered English in the late Middle English period (around the 15th century), borrowed from Old French or directly from the Latin root efficere, meaning 'to bring about, accomplish', from ex- ('out') plus facere ('to make or do'). The same Latin verb gives us effective, efficacy, and effectuate, making these true siblings of effectualness. The abstract noun effectualness has been in use since at least the early modern period as a means of expressing the quality denoted by its adjective.
