Editing Letter case (section)

=== Multi-word proper nouns ===
Single-word [[proper nouns]] are capitalised in formal written English, unless the name is intentionally stylised to break this rule (such as [[e e cummings]], [[bell hooks]], [[eden ahbez]], and [[danah boyd]]).

Multi-word proper nouns include names of organisations, publications, and people. Often the rules for "title case" (described in the previous section) are applied to these names, so that non-initial articles, conjunctions, and short prepositions are lowercase, and all other words are uppercase. For example, the short preposition "of" and the article "the" are lowercase in "Steering Committee of the Finance Department". Usually only capitalised words are used to form an [[acronym]] variant of the name, though there is some variation in this.

With [[personal names]], this practice can vary (sometimes all words are capitalised, regardless of length or function), but is not limited to English names. Examples include the English names [[Tamar of Georgia]] and [[Catherine the Great]], "[[van (Dutch)|van]]" and "der" in [[Dutch name]]s, "[[von]]" and "zu" in [[German name|German]], "de", "los", and "y" in [[Spanish naming customs|Spanish names]], "de" or "d'" in [[French name]]s, and "ibn" in [[Arabic name]]s.

Some surname prefixes also affect the capitalisation of the following internal letter or word, for example "Mac" in [[Surname#Celtic compound names|Celtic names]] and "Al" in Arabic names.
