Reduplication is a process by which the root or stem of a word, or part of it, is repeated. Alternative terms include cloning, doubling, duplication, and repetition. Reduplication has a grammatical function in some languages, such as plurality or intensification. It is also used to derive new words. The process of anthroponymy, or naming people, is frequently creative, and provides examples of this.
During immigration many Arabs or others who use the Arab naming structure do not have a family name but take their father's name as their "last name". Most immigrants from the Arab world usually take their paternal grandfather's name as their last name.
Reduplication in human names is sometimes used with hypocorisms, i.e., informal short versions of names. It is commonly used this way in French and Chinese, e.g., the French name Louise becomes Loulou as a diminutive. The nicknames and fictional characters below include other examples.
