Etymology
The term 'microarray' is a modern scientific compound, formed in the late 20th century. Its first element, 'micro-', derives from the ancient Greek mikros, meaning "small", a root pervasive in scientific vocabulary to indicate a scale requiring magnification. The second element, 'array', entered English via Old French from a Germanic origin, carrying the core sense of an orderly arrangement or marshaling of items. The word's logic is perfectly literal: it names a technology consisting of a very small-scale ('micro-'), orderly grid ('array') of molecular samples, enabling simultaneous analysis of thousands of data points. This transparent compounding follows a long tradition in English of creating precise technical terms from classical and Germanic roots.
Analysis
micro: From Greek mikros, meaning "small". A combining form used in English to denote something extremely small or involving a microscope. array: From Old French arei, meaning "order, arrangement", ultimately from a Germanic source. A noun denoting an ordered arrangement or display of items.
