'accidentally-inclined' originates from the combination of 'accidentally' and 'inclined', where 'accidentally' is derived from 'accident', meaning 'an unforeseen event', and 'inclined' from Latin 'inclinare', meaning 'to lean'.

'accidentally' evolved from the Old French 'accident', and 'inclined' from the Latin 'inclinare', eventually forming the modern English term 'accidentally-inclined'.

Initially, 'accidentally' meant 'by chance', and 'inclined' meant 'leaning towards'. Together, they evolved to describe a tendency to experience accidents.
