'tastelessly-done' originates from the English word 'tasteless,' where 'taste' meant 'aesthetic judgment' and the suffix '-less' indicated 'without.'

'tasteless' evolved from the Middle English word 'tasteles,' which meant 'lacking flavor or aesthetic appeal,' and eventually became the modern English word 'tasteless.'

Initially, it meant 'lacking flavor,' but over time it evolved into its current meaning of 'lacking aesthetic appeal.'
