Relocation comes from relocate + -ion, ultimately from Latin locare ('to place'), from locus ('place'). The historical chain includes Latin locare and Latin locus. The quoted older senses, "to place" and "place", supply the semantic anchors for relocation. The formation is best read as suffixal and borrowed: the word relocation carries its older form-history into a compact English lexical shape. In present English it is used as a noun, "the act of moving to a new location". Related English forms include relocate, locate, and location. The result is a noun whose etymology preserves both the older form and the later English specialization.
