Why is spinach a herb?

Spinach is classified as a herb because it is a leafy green plant that is primarily used for its edible leaves rather than for its seeds or roots. In culinary terms, herbs are often defined as plants with flavorful or aromatic leaves used as seasonings or ingredients. Spinach fits this definition, as its tender leaves are commonly used in salads, soups, and various dishes. Additionally, it is a member of the Amaranthaceae family, which includes many other leafy vegetables.
