Etymology: Apsidal comes from "apside," itself borrowed from Latin "absis" (or "apsis"), which in turn came from Greek "hapsis," meaning "arch," "vault," or "wheel-rim." The Greek root traces back to a Proto-Indo-European root meaning "to fasten," and the notion of a curved or vaulted structure runs all the way through the word's history. A Latin-derived noun for a rounded recess became the name for the half-domed alcove at the end of a church, where the altar and clergy sat, and that architectural sense is the one the adjective still points to. The adjective itself is a simple formation: "apside" plus the English suffix "-al," meaning "of or relating to." Its roots run through Latin "-alis," which passed into English via Old French and Middle English, so the suffix is ancient even though the adjective is a modern technical one. Apsidal therefore describes anything shaped like such an alcove, from a rounded church end to a curved wall in a building or a rounded end of an orbit.
