The word 'starchier' is derived from 'starchy' (from the word 'starch', which comes from Old French 'esparge', meaning a substance obtained from plants) and the suffix '-ier' (meaning more). The term 'starchier' refers to something that has more starch or is more like starch in texture or quality.
Think of 'starch' as a plant-based substance that makes things 'more' like starch when you add '-ier' — that's why 'starchier' means having more starch.
