'seasonally' originates from the word 'seasonal,' which is derived from the Latin word 'sationem,' meaning 'a sowing or planting.'

'seasonal' evolved from the Old French word 'saison,' which meant 'a sowing or planting,' and eventually became the modern English word 'seasonal.'

Initially, it referred to 'a time for sowing or planting,' but over time it evolved into its current meaning of 'related to the seasons.'
