andwithout

Andwithout is a term used in theoretical linguistics and logic to denote a proposed compound connective that combines a standard conjunction with the negation of a second conjunct. In this usage, andwithout(A,B) expresses A together with ¬B, effectively encoding a conjunction of A and the negation of B within a single operator.

Semantics and syntax: The core interpretation is A ∧ ¬B. It is typically analyzed as a coordination device that takes two propositions, A and B, and yields a truth condition equivalent to A being true while B is false. Proponents argue it can simplify analyses of statements where a positive claim must be asserted while a related counterclaim is denied in the same clause. Syntactically, andwithout is usually treated as a coordination marker with two internal branches: the first projecting A, the second incorporating the negated B. It is not part of established natural-language grammar and remains mainly a theoretical device.

History and usage: The term andwithout originated in speculative discussions in the 21st century about how languages encode complex coordination and negation. It has not gained broad empirical support and is not described as a stable category in major grammars, but it appears in some theoretical papers and pedagogical examples to illustrate the interaction of conjunction and negation.

Example and related terms: In formal notation, andwithout(A,B) = A ∧ ¬B. For instance, with A = "The policy is enacted" and B = "the measure is approved," andwithout(A,B) asserts "The policy is enacted and the measure is not approved." Related concepts include conjunction, negation, and exclusive or as alternative ways to express similar ideas.
