Logical connectives can be used to link zero or more statements, so one can speak about n-ary logical connectives. The boolean constants True and False can be thought of as zero-ary operators. Negation is a unary connective, and so on.
a set of operator symbols, called connectives, [18] [1] [50] logical connectives, [1] logical operators, [1] truth-functional connectives, [1] truth-functors, [37] or propositional connectives. [ 2 ] A well-formed formula is any atomic formula, or any formula that can be built up from atomic formulas by means of operator symbols according to ...
The connectives are usually taken to be logical constants, meaning that the meaning of the connectives is always the same, independent of what interpretations are given to the other symbols in a formula. This is how we define logical connectives in propositional logic: ¬Φ is True iff Φ is False. (Φ ∧ Ψ) is True iff Φ is True and Ψ is True.

English: The sixteen logical connectives ordered in a Hasse diagram.They are represented by: logical formulas; the 16 elements of V 4 = P^4(); Venn diagrams; The nodes are connected like the vertices of a 4 dimensional cube.
Various subsets of the sixteen binary connectives (e.g., {∨,&,→,~}, {∨,~}, {&, ~}, {→,~}) are themselves functionally complete in that they suffice to define the remaining connectives. In fact, both NAND and NOR are sole sufficient operators, meaning that the remaining connectives can all be defined solely in terms of either of them ...
Clauses may end no more than one clause final connective. Subordinating connectives are used to create dependent clauses. In clauses, the following order generally holds: (Connective) (Subject) (Object) (Adverb) Verb (Connective) There are occasional examples of S and/or O occurring after the verb, always with animates.
