Definition of truth value in English:

truth value

noun

Logic
  • The attribute assigned to a proposition in respect of its truth or falsehood, which in classical logic has only two possible values (true or false).

    • ‘The examples you gave are both imprecise statements, the first more so than the second, but if you fully qualified them then it could be possible to assign a binary truth value to each.’
    • ‘It lacks a classical truth value as does the odd sentence ‘The present king of France is bald.’’
    • ‘For example, the truth value of a proposition symbolized as p & q depends upon the truth-values of p and of q taken separately.’
    • ‘If it was true, then its truth was a fact about the past; if the past is now unchangeable, then so is the truth value of that past utterance.’
    • ‘Some have claimed that even if future events have a truth value, they are logically unknowable.’
