(i)
(A) The English noun "see" is explained better (than Holy See, see (b) ) in
episcopal see https://en.wikipedia.org/wiki/Episcopal_see
(means "the area of a bishop's ecclesiastical jurisdiction. * * * The word see is derived from Latin sedes, which in its original or proper sense denotes the seat or chair that, in the case of a bishop, is the earliest symbol of the bishop's authority. This symbolic chair is also known as the bishop's cathedra, and is placed in the diocese principal church, which for that reason is called the bishop's cathedral, from Latin ecclesia cathedralis [in Latin, cathedralis is the adjective form of noun feminine cathedra], meaning the church of the cathedra. The word throne is also used, especially in the Eastern Orthodox Church, both for the seat and for the area of ecclesiastical jurisdiction. The term 'see' is also used of the town where the cathedral or the bishop's residence is located") (citations omitted).
(B) etymology:
* bishop (n) https://www.etymonline.com/word/see#etymonline_v_23105
This explains "episcopal" see.
* see (n): " * * * from Latin sedem (nominative [noun feminine] sedes) 'seat, throne, abode, temple,' related to [verb] sedere 'to sit' * * *" https://www.etymonline.com/word/see#etymonline_v_23105
As a Latin noun, sedes (nominative case) is the dictionary form, not sedem (which is accusative case, used to signify direct object of a transitive verb).
* cathedral (n): " * * * from Latin [noun feminine] cathedra 'an easy chair (principally used by ladies)' * * * " https://www.etymonline.com/word/cathedral
Compare Latin-English dictionary:
