What is the meaning of the prefix 'Meso-'?

The prefix 'Meso-' originates from the Greek word 'mesos,' which translates to 'middle' or 'intermediate.' It is commonly used in various scientific and technical contexts to denote something that is situated in the middle or between two other points. For example, in biology, terms like 'mesophyll' refer to the middle layer of leaf tissue, and in geography, 'Mesoamerica' refers to the region that lies in the middle of North America and South America. This understanding underscores the importance of the prefix in defining the spatial or relative position of an object, concept, or phenomenon in relation to others.
