Etymology

Origin of propolis

1350–1400; < Latin < Greek própolis bee glue, literally, outskirts of a city ( see pro- ², -polis), apparently originally the name for a structure around the entrance to a hive, hence applied to the glue from which it was made; replacing Middle English propoleos < Medieval Latin, for Latin propolis as above
