'analyzer' originates from English, specifically from the verb 'analyze,' which comes from French 'analyser,' based on the Greek 'analyein,' where 'ana-' meant 'up' and 'lyein' meant 'to loosen.'

'analyze' was formed in English from the French 'analyser,' which itself was based on the Greek 'analyein.' The noun form 'analyzer' was created in English by adding the '-er' suffix to 'analyze.'

Initially, it meant 'one who analyzes or a device that analyzes,' and this meaning has remained consistent in modern usage.
