Sense: noun/1
Flour is a fine powder made by grinding cereal grains, especially wheat, and is the main structural ingredient in baking thanks to its gluten-forming proteins. Meal is ground more coarsely — cornmeal feels gritty compared to smooth flour, and it is not suitable for the same baked goods. Starch is a pure carbohydrate extracted from plants such as corn or potatoes; it thickens sauces but lacks the protein needed for dough that rises. Powder is a very broad term that covers any substance reduced to fine particles — face powder, curry powder, and washing powder are all powders, but none of them is flour. In a kitchen context, 'flour' without a qualifier means wheat flour; anything else must be specified (rice flour, almond flour, etc.).

Etymology
The word 'flour' comes from Middle English 'flour', which was the same word as 'flower'. In Old French, 'flor' meant both 'flower' and 'the finest part' of something. Grain that had been finely ground was considered 'the flower of the wheat' — the best part. Over time, the cooking sense separated in spelling, but the connection to 'flower' remains visible in the word 'flourish' (to grow well).
