'self-propose' originates from the combination of 'self,' meaning 'oneself,' and 'propose,' meaning 'to put forward an idea or plan for consideration.'

The term 'self-propose' evolved from the practice of individuals nominating themselves for roles or positions, combining the reflexive 'self' with the action 'propose.'

Initially, it meant 'to propose oneself for a role,' and this meaning has largely remained the same in modern usage.
