What is the meaning of the prefix 'macro'?

The prefix 'macro' is derived from the Greek word 'makros,' which means 'large' or 'long.' In medical terminology and related fields, 'macro' is often used to denote something that is large in size, extent, or capacity. For example, in macrosomia, a term used in medicine, it refers to a newborn with an excessive birth weight.

The other options relate to different concepts: 'few' implies a small number, 'small' indicates a reduced size, and 'under' suggests something being beneath or lesser in degree. These meanings contrast with the definition of 'macro,' which emphasizes a larger scale.
