Have you considered that sugar is neither vegetable nor fruit, but more properly considered a spice, in the same class with pepper? Vegetables and fruits are normally eaten for themselves. Spices, like sugar, are used to add flavor to fruits or vegetables.
No, I never considered sugar as a spice, but you have kindly illuminated me.
But alas because a spice is something that grows out of the ground, it
must be either a fruit or a vegetable.
I'm still sticking with the definition the rancher with the deer-killing truck told me.
As an aside, it's a very peculiar sort of life, being deaf; one knows what a thing is for, or how it works, long before one is told the name of the thing.
As the local mechanic will verify in real life, I tend to understand what a part in an engine does, and how it works, but always mess up when giving it a name.
It's embarrassing, always asking people for the name of something that one sees, as it gives the impression one is stupid.
When I get around to winning the Powerball lottery, one person I'm putting on the payroll is someone whose sole job is to tell me the names of phenomenons that one encounters in everyday life, so as to save me embarrassment and humiliation.
