meat-and-potatoes

the phrase "meat and potatoes" originated in the early 20th century as a literal descriptor of a simple, hearty, and fundamental meal, particularly in american and british cultures where these items were dietary staples. by the mid-20th century, it began to be used figuratively as an adjective to describe anything that is basic, substantial, and without frills, drawing a direct metaphorical link from the foundational nature of the meal to the essential nature of a subject. this evolution exemplifies a common linguistic process where a concrete, culturally resonant image becomes a metaphor for core or fundamental qualities, shedding its literal components to form a new, unified lexical item.

this is a fixed compound adjective formed from two common nouns joined by a conjunction. it is treated as a lexical unit and cannot be meaningfully segmented into productive morphemes for analysis.
