What does inadmissibility mean?
Inadmissibility is a formal noun meaning the condition of not being admitted or allowed to be considered. Its principal legal use refers to evidence, testimony, or other material that a court excludes because it is barred by an evidentiary rule or otherwise unsuitable for the case. The word is also used more broadly for things that cannot be accepted, included, or relied upon because they violate a standard or reveal an unacceptable defect. In legal contexts, inadmissibility is distinct from relevance: evidence may be relevant to an issue and still be inadmissible because of a procedural or constitutional rule. The related adjective is inadmissible, and the adverb is inadmissibly. Because the term is precise and specialized, it is especially useful in legal, academic, and formal discussions where the reasons for exclusion or non-acceptance need to be identified clearly.

In court, the question is often not whether evidence is relevant, but whether it is legally allowed to enter the record at all.

Where does inadmissibility come from?
Inadmissibility was formed in the 19th century from the Latin-derived adjective inadmissible, meaning “not allowable” or “not to be admitted,” with the suffix -ity forming a noun of condition. The underlying Latin verb admittere meant “to allow to enter” or “to admit,” built from ad- “to” and mittere “to send.” The related English word admissible retains the affirmative sense, while admissibility names the quality of being allowable or eligible. Cognate forms in other languages preserve the same Latin roots, including French inadmissible and admissible.
