MUTUAL, a relative term, denoting something
that is reciprocal between two or more persons.

Thus we say, mutual assistance, mutual aversion, &c.
There are mutual or reciprocal duties, offices, &c. be-
tween superiors and inferiors; as the king and his sub-
jects, the master and his servants, &c.

Vaugelas makes a distinction between mutual and re-
ciprocal
: mutual, according to him, is understood of
what is between two only; and reciprocal, of what is
between more than two: but this distinction is little
regarded in common use.
