Episcopal see

[1][2] Phrases concerning actions occurring within or outside an episcopal see are indicative of the geographical significance of the term, making it synonymous with diocese.

The church in which it is placed is for that reason called the bishop's cathedral, from Latin ecclesia cathedralis, meaning the 'church of the cathedra'.

The idea of a see as a sovereign entity is somewhat complicated due to the existence of the twenty-three Particular Eastern Catholic Churches.

Both the Western Church and its Eastern Catholic counterparts reserve some level of autonomy, yet each also is subdivided into smaller sees (dioceses and archdioceses).

Certain bishops may be granted additional administrative duties over wider regions (as in the idea of the Pentarchy), but these powers are limited and never extend over the entire Church.
