'easygoing' originates from the combination of 'easy' and 'going', where 'easy' meant 'not difficult' and 'going' referred to 'movement or progress'.

'easygoing' evolved from the Middle English word 'easie' and 'going', eventually becoming the modern English word 'easygoing'.

Initially, it meant 'progressing without difficulty', but over time it evolved into its current meaning of 'relaxed and tolerant'.
