Quick answer

In Webster's Revised Unabridged Dictionary (1913), "season" is labeled noun. Its etymology is recorded as: "[OE. sesoun, F. saison, properly, the sowing time, fr. L. satio a sowing, a planting, fr. serere, satum, to sow, plant; akin to E. sow, v., to scatter, as seed.]" The selected historical definition says: "One of the divisions of the year, marked by alterations in the length of day and night, or by distinct conditions of temperature, moisture, etc., caused mainly by the relative position of the earth with respect to the sun. In the north temperate zone, four seasons, namely, spring, summer, autumn, and winter, are generally recognized. Some parts of the world have three seasons, -- the dry, the rainy, and the cold; other parts have but two, -- the dry and the rainy."
