2. Sentence (mathematical logic) - Wikipedia

   en.wikipedia.org/wiki/Sentence_(mathematical_logic)

   Sentences are then built up out of atomic sentences by applying connectives and quantifiers. A set of sentences is called a theory; thus, individual sentences may be called theorems. To properly evaluate the truth (or falsehood) of a sentence, one must make reference to an interpretation of the theory.

3. Propositional formula - Wikipedia

   en.wikipedia.org/wiki/Propositional_formula

   In propositional logic, a propositional formula is a type of syntactic formula which is well formed. If the values of all variables in a propositional formula are given, it determines a unique truth value. A propositional formula may also be called a propositional expression, a sentence, [1] or a sentential formula.

4. Interpretation (logic) - Wikipedia

   en.wikipedia.org/wiki/Interpretation_(logic)

   In this way, the truth value of the compound sentence is defined as a certain truth function of the truth values of the simpler sentences. 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.

5. Propositional calculus - Wikipedia

   en.wikipedia.org/wiki/Propositional_calculus

   Propositional logic, as currently studied in universities, is a specification of a standard of logical consequence in which only the meanings of propositional connectives are considered in evaluating the conditions for the truth of a sentence, or whether a sentence logically follows from some other sentence or group of sentences.

6. Atomic sentence - Wikipedia

   en.wikipedia.org/wiki/Atomic_sentence

   A sentence is a wff in which any variables are bound. An atomic sentence is an atomic formula containing no variables. It follows that an atomic sentence contains no logical connectives, variables, or quantifiers. A sentence consisting of one or more sentences and a logical connective is a compound (or molecular) sentence.
