To give an appearance of foolishness to; to render wholly futile or ineffectual, usually in a degrading or frustrating way.
A calm virility and a dreamy humor, marked contrasts to her level-headedness—into these moods she slipped sometimes as a refuge. She could do the most prosy things (though she was wise enough never to stultify herself with such "household arts" as knitting and embroidery), yet immediately afterward pick up a book and let her imagination rove as a formless cloud with the wind. Deepest of all in her personality was the golden radiance that she diffused around her. As an open fire in a dark room throws romance and pathos into the quiet faces at its edge, so she cast her lights and shadows around the rooms that held her, until she made of her prosy old uncle a man of quaint and meditative charm, metamorphosed the stray telegraph boy into a Puck-like creature of delightful originality.
—F. Scott Fitzgerald This Side of Paradise (1920)
