Not cut into pieces or slices.
I prefer to buy unsliced bread so I can cut it as I like.
Unsliced → It is formed from "un-" (meaning not) and "sliced" (from the verb "slice", which comes from Old French *slicer*, meaning to cut). The word "unsliced" means not cut into slices.
Think of something that is 'not' ('un-') 'cut' ('slicer') into pieces — that's why unsliced means it remains whole.
