buckwheat: [16] Buckwheat has no connection with male deer. The buck- element is related to the English word beech, and the name comes from the resemblance of buckwheat (the seeds of a plant of the dock family) to the three-sided seeds of the beech tree. The word was actually borrowed from Middle Dutch boecweite, meaning literally ‘beechwheat’. => beech[buckwheat etymology, buckwheat origin, 英语词源]
