Etymology

Origin of communication

First recorded in 1375–1425; Middle English communicacioun, from Middle French, from Latin commūnicātiōn-, stem of commūnicātiō, equivalent to commūnicāt(us) ( see communicate) + -iō -ion

Explanation

Good communication is at the heart of good relationships. Communication is the process of giving information or ideas to someone, as by using words, actions, or sounds. In the plural form, communications has a few specialized meanings: a field of study, a profession, or a system involving the sending of information to people by the use of technology such as radio or satellite. In these senses, communications can be used with a singular or plural verb. The noun communication is from Latin communicare "to share, participate" (from communis "common") plus the suffix –ion "an act or process."
