Double placenames prominently feature the

s of two or more constituents in double-barrelled form rather than invent a new name. This is often out of consideration for local sensitivities, since the smaller entity may resent its takeover, and may demand its symbolic perpetuation within an amalgamated name so as to propagate the impression of a merger between equals.

Styles

In their English forms, the conjoined names may have the following patterns: * concatenation, e.g.

The punctuation and capitalization practices in written English vary: * merging into one word without an intermediate space, e.g.

may sometimes be attempted, but many style guides recommend against this in formal English-language use. Three-word names for two-part entities are often ambiguous. For example, it may not be clear whether North Rhine-Westphalia is an amalgamation between the north part of the

While this problem does not arise in German, no entirely satisfactory punctuation of such names has been established in English. In the above case, the hyphen is often omitted because it is misleading. It has been proposed that this state's name be punctuated "North-Rhine/Westphalia" in English, but the solidus or forward slash is also ambiguous.
