high grade
Premium rating category
High grade describes superior quality or rank: high-grade steel, high-grade tumors (more aggressive in medical contexts).
The hyphenated form works as an adjective before nouns.
As a verb, to high-grade is to selectively take the best portions—originally mining slang for stealing rich ore, now extended to cherry-picking the most valuable items from any collection: He high-graded the estate sale before it opened to the public.
