'trailblazer' originates from the combination of 'trail' and 'blaze,' where 'trail' meant 'a path or track' and 'blaze' meant 'to mark a path with blazes or marks.'

'trailblazer' evolved from the practice of marking trails in forests by cutting marks into trees, which was known as 'blazing a trail.'

Initially, it meant 'to mark a path,' but over time it evolved into its current meaning of 'being a pioneer or innovator.'
