An archaic or legal term for a person who transfers or conveys property to another; one who alienates.
From alien as a verb + -er (a suffix forming agent nouns). Alternative to alienator, appearing in older English legal documents.
'Aliener' and 'alienator' both mean the same thing in law—a person transferring property—but 'aliener' is the older, more archaic form, showing how English legal vocabulary evolved over centuries.
