'hands-on' originates from the English words 'hand' and 'on', where 'hand' refers to the physical part of the body used for manual tasks and 'on' indicates involvement or engagement.

'hands-on' evolved from the literal use of 'hand' and 'on' to describe direct involvement or practical experience.

Initially, it meant 'using one's hands', but over time it evolved into its current meaning of 'involving active participation or practical experience'.
