Analogical change

In language change, analogical change occurs when one linguistic sign is changed in either form or meaning to reflect another item in the language system on the basis of analogy or perceived similarity. In contrast to regular sound change, analogy is driven by idiosyncratic cognitive factors and applies irregularly across a language system. This leads to what is known as Sturtevant's paradox: sound change is regular, but produces irregularity; analogy is irregular, but produces regularity.^[1]
