'randomly-positioned' originates from the combination of 'randomly' and 'positioned', where 'randomly' is derived from 'random', meaning 'without a definite aim, direction, rule, or method', and 'positioned' is the past participle of 'position', meaning 'to place in a particular location'.

'Randomly' evolved from the Middle English 'randoun', meaning 'impetuous course', and 'positioned' from the Latin 'positio', meaning 'a placing'.

Initially, 'randomly' meant 'impetuous course', but over time it evolved to mean 'without a definite aim or method'. 'Positioned' has largely retained its original meaning of 'placed in a location'.
