'randomly-executed' originates from the combination of 'randomly' and 'executed'. 'Randomly' comes from 'random', which has roots in Old French 'randir', meaning 'to run'. 'Executed' comes from Latin 'executus', the past participle of 'exsequi', meaning 'to follow out'.

'randomly-executed' combines the adverb 'randomly' with the past participle 'executed', forming a compound adjective in modern English.

Initially, 'randomly' meant 'without definite aim or direction', and 'executed' meant 'carried out'. Together, they describe actions done without a specific plan.
