The word ‘tax’ first appeared in the English language only in the 14th century. It derives from the Latin taxare which means ‘to assess’. Before that, English used the related word ‘task’, derived from Old French. For a while, ‘task’ and ‘tax’ were both in common use, the first requiring labour, the second money.
