A late Middle English word dating back to 1375–1425; see origin at in- 3, effectual
Explanation
If you are a coach with a losing team that doesn't listen to you, don't be surprised if you are called ineffectual. It means too weak to produce the desired effect. Ineffectual is similar to ineffective, but while ineffective implies that something simply doesn't work, ineffectual carries with it the idea of weakness too. An old computer might be ineffective for creating state-of-the-art digital presentations; a boss who looks the other way while her employees slack off all day, on the other hand, is ineffectual.
