A papal letter circulated to the bishops and, through them, to the whole church.

The Greek roots

ἐγκύκλιος
enkýklios
circular, general

Literally: going round in a circle

The story of the word

The Greek adjective meant going the rounds, and enkyklios paideia, education in the round, is the phrase that gave us encyclopedia. Bishops were sending circular letters long before the form had rules; Benedict XIV set the modern pattern in 1740. Each one is known by its opening Latin words, which is why the great labour encyclical of 1891 is called Rerum Novarum.
