Etymology: The suffix "-ness" in English is a productive way to form nouns that express a state, quality, or condition derived from adjectives or nouns. It has its roots in Old English, where "-nes(s)" was commonly used to turn adjectives into abstract nouns, such as "happiness" from "happy." This suffix has persisted into Modern English with much the same function, giving rise to numerous abstract nouns that describe qualities or states of being. The base "stem" in this case most likely refers to its general meaning as the main body or support of a plant, or metaphorically, the core or root of something. The word "stem" itself derives from Old English "stemn" or "stefn," meaning the trunk of a tree or the main stalk of a plant. Over time, "stem" has extended into various fields including linguistics, biology, and even technology, always retaining the sense of a central supporting structure. When combined, the noun formed by adding "-ness" to "stem" creates a term that refers to the quality or state of being like a stem — that is, possessing the essential or foundational characteristics of a stem. While this is not a commonly encountered word in everyday usage, it might appear in specialized contexts such as botany or metaphorical language, where one wants to emphasize the core or foundational nature of something. The formation of abstract nouns in this way is typical of English’s flexibility in word-formation processes, allowing speakers to create new terms as needed by combining existing roots with suffixes. This particular construction likely arose naturally by analogy with other "-ness" nouns and does not have a singular recorded moment of coinage. It reflects the tendency of English to adapt simple roots into more complex conceptual terms.
