MU'TU-AL, a. [Fr. mutuel; L. mutuus, from muto, to change.]

Reciprocal; interchanged; each acting in return or correspondence to the other; given and received. Mutual love is that which is entertained by two persons each for the other; mutual advantage is that which is conferred by one person on another, and received by him in return. So we say, mutual assistance, mutual aversion. And what should most excite a mutual flame, / Your rural cares and pleasures are the same. Pope.
