Morphology

microarray = array (semi-transparent) = micro + array

The word is built transparently from 'micro-' + 'array', but the technical biological sense is specialized rather than fully predictable for an average learner.

Etymology

Microarray combines micro- meaning 'small', as in microscope, and array meaning 'a neat arrangement'. So a microarray is a small, carefully arranged set of tiny spots used in labs to test many genes at once.
