Origins

Meanings 1–6, 9–13

The root is Proto-Indo-European *sed-, which gave Latin assidēre (ad- "to, towards" + sedeō "sit"), then the Old French verb asseoir ("to sit down") and the noun assise ("assize"). A shortened form of assise became Middle English syse, sise ("regulation, control, limit"). In use since the 14th century, the word first referred to a "law or regulation that determines the amount to be paid."

Meanings 7–8

From Middle English syse, of unclear origin. It is related to Old Italian sisa ("a glue used by painters"), and is perhaps ultimately connected to size meaning "amount," or perhaps shortened from assisa, from assiso ("seated").
