reduplicant

A reduplicant is a linguistic phenomenon where a word, or part of a word, is repeated. This repetition can serve various grammatical or semantic functions depending on the language. For instance, in some languages, reduplication is used to indicate plurality, intensity, or continuity. It is a common feature across many of the world's languages, though its specific form and function vary widely.

In English, reduplication is not a productive grammatical process for forming new words in the way it is in other languages. However, examples exist, often in the form of onomatopoeia, such as "choo-choo" for a train sound, or "drip-drip" to describe water. Certain phrases also exhibit reduplication, like "bye-bye" or "wishy-washy," which often carry a sense of informality or diminutiveness. Adverbs like "very, very" can also be seen as a form of reduplication to emphasize the degree.

Across languages, reduplication can be total, where the entire word is repeated, or partial, where only a part of the word is repeated. The repeated element might be a syllable, a root, or an affix. The purpose can range from grammatical marking, such as indicating a verb's aspect or a noun's number, to semantic modification, like intensifying the meaning or creating a sense of distribution. For example, in Tagalog, reduplication is used to form future tense verbs. In some African languages, it can denote plurality or intensity. The study of reduplication falls under morphology, the branch of linguistics that studies word structure.
