What does arrogation mean?
Arrogation is the act of taking or claiming something for oneself without any right to do so, most often applied to the unjustified seizure of power, authority, or privilege. When a ruler assumes powers that belong to a parliament, or an official claims prerogatives never granted to them, commentators may speak of the 'arrogation' of those powers. The word derives from the Latin 'arrogare', meaning to claim or attribute to oneself, and it carries an unmistakably negative connotation: it implies presumption, overreach, and a disregard for legitimate boundaries. Formal and relatively rare, arrogation appears chiefly in legal, political, and scholarly contexts rather than everyday conversation. It should not be confused with abrogation, which refers to the repeal of a law. A related historical sense survives from Roman law, where arrogatio described the formal adoption of one adult by another — a striking contrast between the word's legal origins and its modern critical use.
The act of taking or claiming something for oneself without right, especially the unwarranted assumption of power, authority, or privilege.
"The tribunal ruled that the agency's arrogation of judicial functions was unconstitutional."
Almost always used in the phrase 'arrogation of' followed by the thing claimed (power, authority, rights).
In Roman law, the formal adoption of a person, usually an adult, into another family with their consent.
"Arrogation required the consent of both the adopting father and the adult being adopted."
A historical, technical sense confined to studies of Roman law.
Rarely pluralized; the word is normally used as an uncountable noun referring to the act in general.
"History records many arrogations of royal power by ambitious ministers."
In ancient Rome, 'arrogatio' was the legal ceremony for adopting an adult son — but in English, arrogation came to mean exactly the opposite: grabbing what isn't yours.

Etymology of arrogation
Arrogation comes from the Latin 'arrogatio', derived from 'arrogare', meaning to claim or attribute to oneself, formed from 'ad-' (toward) and 'rogare' (to ask or propose). In classical Rome, arrogatio was the technical term for the adoption of an adult person into another family. The word entered English in the early 17th century, where its meaning shifted toward the critical sense of unjustified self-claiming. It shares its root with 'arrogate' and, more distantly through the idea of presumptuous self-assertion, with 'arrogance'.
