Surface Forms

carryover singular
carryovers plural

Morphology

carryover = carry (transparent) = over + carry

This technical sense denotes residue that 'carries over' between samples, a direct extension of the phrasal verb meaning and thus inferable from the components. [Postprocessing: moved 'over' from base_words to prefix]

Etymology

Carryover comes from the words carry ('to move') and over ('into the next thing'). Imagine a small drop left on a spoon that goes into the next bowl, so in a lab a carryover is a leftover from one test that can affect the next result.
