What does logicality mean?
Logicality is the quality of thinking or arguing in a way that is clear, consistent, and governed by valid rules of inference. It refers both to the character of an individual argument and, more broadly, to the principles of logic as a formal discipline. A piece of reasoning may possess considerable logicality even when its conclusions are unacceptable, because logicality concerns the structure of the reasoning rather than whether the premises are true or the conclusion is desirable. In ordinary discussion, the word is especially useful when examining the coherence of an argument, a decision, or a set of claims. It is more formal than words such as reasonableness and more specifically concerned with the validity and consistency of thought. The term is common in philosophy, mathematics, law, science, and academic criticism, where the distinction between logical soundness and factual truth is important.

Where does logicality come from?
Logicality was formed in English from logical plus the suffix -ity, meaning the quality or state of being something. The adjective logical comes through Latin from Greek logikos, which is derived from logos, meaning “word,” “reason,” or “account.” The same Greek root underlies logic, logistic, and logogram, reflecting its broad association with reason, proportion, and language.
