It is an Anglicism that is used in Spanish to name devices that are handled or held with one hand, especially those of communication, and is pronounced jandi. The first portable radio transceivers were loaded into a backpack, but the switch button between transmission or reception and the microphone with the speaker was a set that was carried with the hand as a handy. With the reduction in size in electronics, all radio moved into the category of handy. It has its etymology in the English voice hand (jand "hand"). See walkie talkie .
