'randomly-situated' originates from the combination of 'randomly' and 'situated'. 'Randomly' comes from 'random', which has roots in Old French 'randir', meaning 'to run'. 'Situated' comes from Latin 'situatus', meaning 'to place'.

'randomly-situated' evolved from the combination of 'randomly' and 'situated', which were used separately in Middle English and later combined in modern English.

Initially, 'randomly' meant 'without definite aim or direction', and 'situated' meant 'placed'. Together, they convey the idea of being placed without a specific pattern.
