'analysers' originates from English, specifically the word 'analyse', where 'analyse' meant 'to examine in detail'. The '-er' suffix denotes 'one who does'.

'analyse' comes from French 'analyser', which in turn comes from Medieval Latin 'analysare', based on Greek 'analusis' meaning 'a breaking up'. The plural 'analysers' simply adds the English plural '-s'.

Initially, 'analyser' meant 'one who analyses', but it now also refers to a device or instrument that performs analysis.
