English: “Break” — might [into] two? The verse says “pieces.” If “pieces,” might one make it crumbs? The verse says “it” — it into pieces, and not pieces into [further] pieces.
Miyut of degree of breaking — neither left whole nor reduced to crumbs.
The minchah is broken into pieces, not left whole and not reduced to crumbs. The verse’s language teaches a middle path: break it into pieces, but do not continue breaking those pieces into still smaller fragments.
