Morphology

subsampling = subsample (transparent) = sub + sample + ing

The verb 'subsample' is a clear combination of 'sub-' + 'sample' meaning 'take a smaller sample', and adding '-ing' forms the process/gerund.

Etymology

Subsampling comes from sub- meaning 'under' or 'smaller' and sample meaning 'a small part'. So subsampling is the act of taking a smaller sample from a larger group, like tasting a tiny piece of a big cake to judge the whole.
