'emotionally-decided' originates from the combination of 'emotionally' and 'decided', where 'emotionally' is derived from 'emotion', and 'decided' is the past participle of 'decide'.

'emotionally' evolved from the Latin word 'emotio', meaning 'a moving, stirring, agitation', and 'decide' comes from the Latin 'decidere', meaning 'to cut off'.

Initially, 'emotionally' referred to the act of being moved or stirred, while 'decide' meant to cut off or determine. Together, they evolved to mean making a decision based on emotions.
