formalprefix

Formalprefix is a term used in linguistics and computational linguistics to describe a prefixal marker that signals formality or politeness in discourse. It refers to any affix placed before a noun, proper name, or title that conveys elevated or formal status, respect, or social distance.

The concept is not universally standardized, but it serves as a descriptive label applied across languages to discuss how formality is encoded morphologically or orthographically. In natural language usage, formal prefixes often appear as honorifics or titles, such as Sir, Dr., Don, Doña, or Mr., before a name, or as prefixes in other languages that elevate the formality of a noun. In many linguistic traditions, dedicated prefixes or pre-nominal forms encode social relations and mode of address.

In natural language processing and related fields, formalprefix can be used as an annotation feature or design pattern to control formality in generation, translation, or address choice. It can be paired with other features such as gender, number, or tense to select an appropriate form of address, or to influence prosody in text-to-speech systems when formality is a factor.
