'praise-motivated' originates from the combination of 'praise' and 'motivated', where 'praise' means 'express approval or admiration' and 'motivated' means 'provided with a reason to act'.

'praise' and 'motivated' were combined in modern English to form the compound adjective 'praise-motivated'.

Initially, 'praise' meant 'to express approval', and 'motivated' meant 'to provide a reason to act'. Together, they evolved to describe someone driven by positive feedback.
