Ambiguity A sentence is ambiguous in a given context if there is more than one possible way to interpret it in that context. A word is ambiguous in a given context if there is more than one possible way to interpret it in that context. See also lexical ambiguity, syntactic ambiguity. Compare vagueness.

Antecedent A conditional statement asserts a relation between two propositions, the antecedent and the consequent. When the antecedent of a true conditional statement is true, the consequent must also be true. Thus the antecedent of 'If John wins then Mary will cry' is 'John wins'; if one accepts both this conditional and its antecedent as true, then one must also accept that Mary will cry.

Argument An argument is a system of propositions comprising one or more premises advanced by the arguer in support of a conclusion. Arguments may be evaluated as valid, inductively forceful, or neither, but not as true or false.

Argument commentary An argument commentary is a short essay that discusses an argument reconstruction, covering the following points: (i) how and why the argument was reconstructed as it was; (ii) the validity or degree of inductive force of the argument; (iii) the truth-values of the premises; (vi) the degree of rational persuasiveness of the argument for relevant audiences, where this is not already addressed by (iii).
