Pronounced: val-ih-DIK-shun, noun
Notes: I didn’t know the meaning of this word; it reminded me of a word I do know
The word stenophagous means “feeding on a limited variety of food”
The word came into English in the 1920s
Background / Comments
I am not sure how “limited” the food has to be to qualify for this word. I remember having a discussion back in high school of food we didn’t like, and one of the class comedians listed “pine cones”. Cutting these out of one’s diet probably doesn’t count as a “limited” variety of food. Our word comes from a combination of two words steno- (narrow; small) and -phagous (feeding on).
