Etymology: Deseasoning is a plain, transparent formation: the verb "season" (from Old French "seisoun", from Latin "satio", "a sowing," related to "serere," "to sow," and so tied to the idea of a fixed time of year) combined with the privative prefix "de-," meaning "remove" or "reverse." Put together, it means to take the seasonal character out of something. The "season" base itself has a telling history: in English it first meant a proper time for something, and the sense of a quarter of the year came later, so the root's oldest idea is timing rather than weather. The word's modern uses follow the same logic. In statistics and economics, deseasonalizing data means removing regular yearly fluctuations, such as holiday retail spikes, so that underlying trends are visible. In agriculture and food processing, it can mean treating produce so it no longer depends on its usual harvest window. Its appearance in English is recent and technical, and dating its first use precisely is beyond what I can confirm.
