English orthography sometimes uses the term proper adjective to mean adjectives that take initial capital letters, and common adjective to mean those that do not. For example, a person from India is Indian. Indian is a proper adjective.
Origin of the terms
The term proper noun denotes a noun that, grammatically speaking, identifies a specific unique entity; for example, England is a proper noun, because it is a name for a specific country, whereas dog is not a proper noun; it is, rather, a common noun because it refers to any one member of a group of dog animals.
In English orthography, most proper nouns are capitalized and most common nouns are not. As a result, the term proper noun has come to mean, in lay usage, a noun that is capitalized, and common noun to mean a noun that is not capitalized. Furthermore, English adjectives that derive from proper nouns are usually capitalized. This has led to the use of the terms proper adjective and common adjective, with meanings analogous to the lay meanings of proper noun and common noun. Proper adjectives are just capitalized adjectives.
Description of proper adjectives
In general, an adjective is capitalized if it means "pertaining to X" where X is some specific person, place, language, or organized group. Most capitalized adjectives derive from proper nouns; for example, the proper adjective American derives from the proper noun America.
Sometimes, an adjective is capitalized because it designates an ethnic group with a shared culture, heritage, or ancestry. This usage asserts the existence of a unified group with common goals. For example, in Canadian government documents, Native and Aboriginal are capitalized.
An adjective can lose its capitalization when it takes on new meanings, such as chauvinistic. In addition, over time, an adjective can lose its capitalization by convention, generally when the word has overshadowed its original reference, such as gargantuan, quixotic, titanic, or roman in the term roman numerals.
An adverb formed from a capitalized adjective is itself capitalized. For example:
- We have regularly received enquiries regarding the availability of Islamic finance products, in particular Islamically compatible finance to purchase both residential and commercial properties.
- There are people who express themselves 'Germanly,' while others have forms of life that are expressed 'Frenchly', 'Koreanly' or 'Icelandicly'.
Other parts of speech
Verbs such as Canadianize are written with a capital letter, though not generally described as proper verbs.
