spinach
Synonym discussion
Sense: noun/1
Spinach, kale, chard, and lettuce are all leafy greens, but they differ in texture, taste, and use. Spinach has the mildest flavour and softest leaves, making it equally suited for raw salads and cooked dishes. Kale is tougher and chewier, so it is often baked into crisps or massaged with oil before being used in salads. Chard has colourful stalks and a slightly earthier, sweeter taste when cooked; it holds its shape better than spinach in stir-fries. Lettuce is the crunchiest and most watery, used almost exclusively raw in sandwiches and salads. The general term 'greens' can refer to any leafy vegetable but is more common in American English for cooked greens like collards or turnip tops.
Etymology
The word 'spinach' entered English in the 14th century from Old French 'espinache', which came from Arabic 'isbānākh', itself borrowed from Persian 'aspanākh'. The plant was originally cultivated in ancient Persia (modern-day Iran and surrounding areas).
