Ineffectiveness → It is formed from "in-" (meaning not) and "effectiveness" (from Latin "effectivus", meaning producing an effect, and the suffix "-ness" which denotes a state or quality). The word describes the state of not producing the desired effect or result.
Think of 'not' ('in-') being combined with 'producing an effect' ('effectiveness') to remember that 'ineffectiveness' means the state of not achieving the intended outcome.
