fromsuch

Fromsuch is a term used in theoretical and computational contexts to describe an inferential operation that derives general conclusions from a set of specific instances. The term is not standardized and appears mainly in niche discussions, exploratory writings, and informal glossaries rather than as a formal method in established disciplines.

Etymology and usage notes: The word combines the preposition from with the demonstrative such. There is no single origin or authority for fromsuch; references tend to arise independently in online discussion and in early 21st century papers that address generalization and rule extraction. In practice, fromsuch functions as a general-purpose indicator rather than a fixed operator.

Definition and interpretation: In broad use, fromsuch signals a move from particular cases to a broader generalization, akin to induction or abstraction. In formal notation, authors may treat fromsuch as an operator F applied to a set X, yielding a generalized rule or property shared by elements of X. The concept is often illustrated with concrete examples and contrasted with alternative formulations that emphasize different inferential steps.

Examples: Fromsuch({apple, banana, cherry}) might yield the generalization that the items in the set are fruit, or that they share an edible property in a given context. In pseudo-code: result = Fromsuch(dataset, condition) then derive rule r that holds for all items in dataset meeting condition.
