Overregularization is the term used to describe when toddlers apply grammatical rules even to words that are an exception to the rule, such as saying "mouses" instead of "mice" or "foots" instead of "feet." This is seen as a normal part of language development and eventually corrects itself as children learn the correct usage through exposure and practice. Underregularization refers to when children fail to apply a grammatical rule to words that should follow it, while hypergeneralization and hypogeneralization are not terms commonly used in developmental psychology.
