randomised

The word 'randomised' is built upon the core concept of 'random', which originally described impetuous speed or force. The modern sense of 'lacking a definite aim or pattern' developed in the 17th century. By adding the verb-forming suffix '-ise', meaning 'to make', the term 'randomise' was created to describe the act of making a process or selection operate by chance. The final '-ed' suffix completes the word, forming either the past tense of the verb or an adjective describing something that has undergone this specific process, a term now central to the methodology of controlled scientific trials and fair lotteries.

Structure: random (by chance) + ise (verb suffix) + ed (adjective/verb suffix) - random: From Old French randon 'impetuosity, speed', of Germanic origin. In this word, it functions as the core root meaning 'by chance, without aim'. - ise: A verb-forming suffix from Old French -iser, from Latin -izare, from Greek -izein. It indicates 'to make, to cause to be'. - ed: A suffix from Old English -ed, -od, -ad. Here, it forms the past tense/past participle of the verb and can also create an adjective meaning 'having been subjected to the action'.
