The compound adjective "thin-sliced" is a modern English formation that transparently combines two native concepts. "Thin" descends from the Proto-Germanic thunnuz, a concept of narrowness or sparseness. "Slice" entered English via Old French but has Germanic roots related to splitting or cleaving. The combination follows a straightforward descriptive logic: the manner of cutting ("sliced") is modified by the quality of the resulting piece ("thin"). This literal construction is widely applied in culinary and analytical contexts to describe objects or data divided into fine, discrete layers.

Structure: thin (having little thickness) + slice (cut into pieces) + ed (adjective suffix) - thin: From Old English þynne, meaning "not thick, slender, sparse." It functions as an adjective describing a small distance between surfaces. - slice: From Old French esclice "splinter," ultimately from a Germanic source. It functions as a verb root meaning "to cut." - ed: A common English suffix forming past participles, which can function as adjectives.
