'april' originates from Latin, specifically the word 'Aprilis', where 'aperire' meant 'to open'.

'april' changed from Old French 'avril' and Middle English 'Aprille' and eventually became the modern English word 'april'.

Initially, it meant 'the (month) of opening' (referring to buds opening in spring), but over time it evolved into its current meaning of 'the fourth month of the year'.
