Is It Ineffective or Ineffective?

So, ineffectual in my mind refers to the state of it having an effect at a specific point in time, either right now or at some definite point in the past.

Is it ineffective or 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.
