arrondissement
UK[əˈrɒndɪsmə̃]US[ˌærənˈdiːsmənt]
n
An administrative district of a large city, especially in France.
n
The largest administrative subdivision of a French department.
Etymology
The word 'arrondissement' entered English directly from French in the late 18th century, retaining its original administrative meaning. In French, it derives from the verb arrondir, meaning 'to round off' or 'to make round', which itself comes from the Old French a (to) and rond (round), ultimately from the Latin rotundus. The suffix -ment forms nouns indicating an action or its result. The term's logic stems from the idea of 'rounding off' or grouping together surrounding territories to form a coherent administrative district, originally applied to the subdivisions of Paris and later to departmental subdivisions in France.
Analysis
This word is a direct loanword from French. It is not productively segmented using English morphemes. Its French components are the verb arrondir (to round, to make round) and the suffix -ment (which forms nouns of action or result).
