uncouthness

I had first thought of Milly's absurdities, to which, in description, I cannot do justice, simply because so many details have, by distance of time, escaped my recollection. But her ways and her talk were so indescribably grotesque that she made me again and again quiver with suppressed laughter. But there was a pitiable and even a melancholy meaning underlying the burlesque. This creature, with no more education than a dairy-maid, I gradually discovered had fine natural aptitudes for accomplishment - a very sweet voice, and wonderfully delicate ear, and a talent for drawing which quite threw mine into the shade. It was really astonishing.
