pertinence

This term describes a precise logical connection between a piece of information and the subject at hand. It carries a formal, analytical tone often found in legal, academic, or professional settings where the validity of an argument depends on the strict applicability of evidence.

Because it is an abstract quality, the word is uncountable. It cannot be pluralized or counted as individual units; instead, it is measured in degrees, such as having little or great pertinence to a topic.
