usage note for mutual

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.
