Completeness has 3 different meanings across 1 category:
the state of being complete and entire; having everything that is needed
"The completeness of the archaeological find was confirmed when every missing bone fragment was finally discovered in the same layer."
(logic) an attribute of a logical system that is so constituted that a contradiction arises if any proposition is introduced that cannot be derived from the axioms of the system
"In formal logic, the completeness of a system guarantees that introducing any statement not derivable from its axioms will inevitably lead to a contradiction."
the state or condition of being complete
"The completeness of the archaeological excavation was ensured by every artifact being recorded and cataloged before moving to the next site."
In plain English: Completeness means having all the necessary parts so that nothing is missing.
"The completeness of her report impressed everyone in the meeting."
Usage: Use completeness to describe the quality of having all necessary parts, such as in reports that lack nothing essential. It is often paired with adjectives like total or absolute when emphasizing an unbroken whole.
Completeness is formed by adding the suffix "-ness" to the word complete. This construction simply indicates the state or quality of being whole and finished.
