four-season

The compound "four-season" is a transparent modern English formation, directly combining the numeral "four" with the noun "season." The word "season" itself has an agricultural origin, deriving from the Latin sationem meaning "a sowing," which evolved in Old French to denote the appropriate time for sowing and, by extension, any characteristic period of the year. The concept of dividing the year into four specific seasons (spring, summer, autumn, winter) is ancient and cross-cultural. Therefore, "four-season" logically builds on this established framework to describe something encompassing or enduring across the entire annual cycle, moving from the literal act of sowing to the abstract idea of year-round applicability.

Structure: four (number) + season (period of the year) - four: From Old English fēower, of Proto-Germanic origin; related to Latin quattuor. Functions as a numerical quantifier. - season: From Old French seson, ultimately from Latin sation- (sowing), from serere (to sow). Functions as the core noun denoting a distinct period.
