köken: Inherited from Middle French chez, from Old French chies, from Latin casa (“house”). Doublet of case. The lack of final -e may be due to contraction in unstressed position; however, it has also been explained as the continuation of a Proto-Romance dative-genitive form case (from Latin casae).
at X's abode · in X's view; as X expresses it in their writings
köken: Originally an unstressed form of hus (“house”) undergoing a development in meaning from "at someone's house" to "with someone" – analogous to the development of Latin casa (“house”) to French chez (“at (the house of)”). Displaced Old Norse hjá.
