schaftlich
Schaftlich is a German adjective derived from the noun Schaft, meaning shaft, stalk, or handle. In principle, schäftlich denotes a relation to, or characteristic of, a shaft. The term is not common in everyday language and does not have a widely standardized definition in major dictionaries. When it appears, it is usually in technical or industrial contexts and may be interpreted as a back-formation or specialized coinage intended to signify “shaft-related” aspects in a given discourse.
Etymology and scope: The word combines Schaft with the productive suffix -lich, which is used to form
Usage and precautions: Given its rarity and lack of standardization, schäftlich is best treated as a niche
