Would'st thou approve thy constancy? Approve first thy wisdom.
This sense, though common a century or two ago, is now rare.
3. To experience; to prove by trial. Not used. See Prove.
4. To make or show to be worthy of approbation; to commend.

5. To like and sustain as right; to commend.
Yet their posterity approve their sayings. Ps. 49.
This word, when it signifies to be pleased, is often followed by of, in which use, it is intransitive; as, I approve of the measure. But the tendency of modern usage is to omit of. "I approve the measure."
