'self-turmoil' is a compound word formed from 'self,' meaning 'one's own person,' and 'turmoil,' which originates from Middle English 'turmoyle,' meaning 'commotion or disturbance.'

'Turmoil' evolved from the Middle English 'turmoyle' and combined with 'self' to form the modern term 'self-turmoil.'

Initially, 'turmoil' referred to external commotion, but in 'self-turmoil,' it signifies internal emotional disturbance.
