Legumes are grains. It's a sub category just like cereal is a sub category. They are all grains.

Only in the "cucumbers are fruit" botanically technically correct but incorrect from common usage standpoint.

Sure, except this is the first time in my life I've seen the term "pulse" used for a vegetable. And, honestly, only in the last 10 years have I been hearing the term legume in common conversation. Grain is definitely the more common term.
