Synonym Study
1. Mutual, reciprocal agree in the idea of an exchange or balance between two or more persons or groups. Mutual indicates an exchange of a feeling, obligation, etc., between two or more people, or an interchange of some kind between persons or things: mutual esteem; in mutual agreement. Reciprocal indicates a relation in which one act, thing, feeling, etc., balances or is given in return for another: reciprocal promises or favors.
Usage note
The earliest (15th century) and still a current meaning of mutual is “reciprocal,” specifying the relation of two or more persons or things to each other: Their admiration is mutual. Teachers and students sometimes suffer from a mutual misunderstanding. Mutual soon developed the sense of “having in common, shared”: Their mutual objective is peace. This latter sense has been in use since the 16th century and is entirely standard. It is occasionally criticized, not on the grounds of ambiguity but on the grounds that the later sense development is somehow wrong. Mutual in the sense of “shared” may have been encouraged by the title of Charles Dickens's novel Our Mutual Friend (1864–65), but Dickens was not the innovator. The fact that common also has the sense “ordinary, unexceptional” and “coarse, vulgar” may have contributed to the use of mutual instead of common in designating a shared friend.

Word Origin and History for mutually
adv.

1530s, from mutual + -ly (2). Mutually exclusive is recorded by 1650s.

mutual

adj.

late 15c., originally of feelings, from Middle French mutuel (14c.), from Latin mutuus "reciprocal, done in exchange," from PIE root *mei- "to change, exchange" (see mutable).

The essence of its meaning is that it involves the relation x is or does to y as y to x; & not the relation, x is or does to z as y to z. [Fowler]
Mutual Admiration Society (1851) seems to have been coined by Thoreau. Mutual fund is recorded from 1950. The Cold War's mutual assured destruction attested from 1966. (Assured destruction was an early 1960s term in U.S. military policy circles in reference to nuclear weapons as a deterrent, popularized c.1964 by Robert McNamara, U.S. Secretary of Defense under Lyndon Johnson, e.g. statement before House Armed Services Committee, Feb. 18, 1965; the mutual perhaps first added by Donald Brennan, conservative defense analyst and a public critic of the policy, who also noted the acronym MAD.)

n.

short for mutual fund, 1971; see mutual.
