'analyze' originates from French, specifically the word 'analyser', which came from Medieval Latin 'analysare', based on Greek 'analusis', where 'ana-' meant 'up' and 'lysis' meant 'a loosening'.

'analyser' in French was adopted into English as 'analyze', and the third person singular present form became 'analyzes' in modern English.

Initially, it meant 'to break up or loosen up', but over time it evolved into its current meaning of 'to examine in detail'.
