What does conclusory mean?
"Conclusory" is an adjective used chiefly in legal and academic contexts to describe a statement, allegation, or argument that asserts a conclusion without supplying the reasoning or evidence needed to support it. A conclusory claim simply declares that something is so, leaving the reader to take it on faith; in practice, this makes it a term of criticism rather than description. When a judge calls a pleading conclusory, the implication is that it fails to meet the standards of substantive argument and may be disregarded. The word derives from Latin roots relating to "concluding," yet its modern force is almost the reverse of "conclusive": where a conclusive argument settles a question decisively, a conclusory one merely gestures at an answer. For writers and readers alike, it names a familiar failure of argument — the confident assertion that never shows its work — and it remains a precise, useful label for that shortcoming.
adjective(Of a statement, argument, or allegation) asserting a conclusion without providing the reasoning or evidence that supports it; unsupported and merely declaratory.
- (Of a statement, claim, or argument) stating a conclusion without presenting the evidence or reasoning that supports it; unsupported by demonstration.
"The judge dismissed the brief as conclusory, noting that it asserted fraud without offering a single supporting fact."
"The plaintiff's allegations were dismissed as conclusory because they named no dates, documents, or witnesses."
"A conclusory paragraph that simply announces its findings will persuade no careful reader."
In legal writing, calling an argument 'conclusory' is a polite way of saying it's all assertion and no evidence — the word sounds like praise but functions as a rebuke.

Etymology of conclusory
"Conclusory" derives from the Latin verb "concludere," meaning "to shut up, enclose, or bring to a close," formed from "com-" (together) plus "claudere" (to shut). It entered English as a learned formation alongside related words such as "conclude," "conclusion," and "conclusive." Its specialized sense — an assertion that states a conclusion without demonstrating it — developed particularly in legal usage, where precision about what has actually been proven matters greatly.
How conclusory is actually used
