Morphology

oversampling = oversample (transparent) = over + sample + ing

Formed by the verb 'oversample' plus the gerundive/nominal suffix '-ing'; the components 'over' + 'sample' are semantically transparent.

Etymology

The word oversampling comes from the parts over- meaning 'more than', like in overcook, and sample meaning a 'small part' or 'example'. So oversampling is taking 'more than' the usual number of people from a group to get better information about them.
