Useless, and thence ridiculous.

Syn. -- Fruitless; ineffectual. -- Useless, Fruitless, Ineffectual. We speak of an attempt, effort, etc., as being useless when there are in it inherent difficulties which forbid the hope of success, as fruitless when it fails, not from any such difficulties, but from some unexpected hindrance arising to frustrate it; as, the design was rendered fruitless by the death of its projector. Ineffectual nearly resembles fruitless, but implies a failure of a less hopeless character; as, after several ineffectual efforts, I at last succeeded.

Useless are all words
Till you have writ "performance" with your swords.
The other is for waiving.

Waiving all searches into antiquity, in relation to this controversy, as being either needless or fruitless.

Even our blessed Savior's preaching, who spake as never man spake, was ineffectual to many.
