etymology
Ultimately from the Latin Feminine noun satio, sationis (sowing, planting), derived from the same root as the Latin verb sero serere, sevi, satum (sow, plant), through the Old French noun seson/ seison/ saison (sowing time) and the Middle English noun sesoun/ seson of the same meaning, combined with the suffix -al, from the Latin suffix –alis (pertaining to).
