Averse to activity, effort, or movement; habitually lazy.

He had carried his cup to the fireplace, and stood leaning against the chimney-piece and looking down on her with an air of indolent amusement. The provocation in her eyes increased his amusement — he had not supposed she would waste her powder on such small game; but perhaps she was only keeping her hand in; or perhaps a girl of her type had no conversation but of the personal kind.
