Usage: Reciprocal, Mutual. The distinctive idea of mutual is, that the parties unite by interchange in the same act; as, a mutual covenant; mutual affection, etc. The distinctive idea of reciprocal is, that one party acts by way of return or response to something previously done by the other party; as, a reciprocal kindness; reciprocal reproaches, etc. Love is reciprocal when the previous affection of one party has drawn forth the attachment of the other. To make it mutual in the strictest sense, the two parties should have fallen in love at the same time; but as the result is the same, the two words are here used interchangeably.

Reciprocal may refer to:
A reciprocal is a linguistic structure that marks a particular kind of relationship between two noun phrases. In a reciprocal construction, each of the participants occupies both the role of agent and patient with respect to the other. For example, the English sentence "John and Mary cut each other's hair", contains a reciprocal structure: John cuts Mary's hair, and Mary cuts John's.
Many languages, such as Semitic languages, Altaic languages or Bantu languages, have special reciprocal morphemes in verbs. English does not, and it generally uses "each other" or some other phrase to indicate reciprocity. Latin uses inter and the reflexive pronoun of the subject of the verb: inter se (between themselves) when the verb is third-person. Most Indo-European languages do not have special markers for reciprocity on verbs, and reciprocal constructions are expressed through reflexivity or other mechanisms. For example, Russian marks reciprocity in intransitive verbs with the suffix -ся (self), which has also reflexive and passive interpretations.
