Final answer:
The incorrect statement about words and generativity is that words are stored in our heads like a dictionary (option A). Our understanding of language involves a complex set of rules for generating new words and using language creatively, which evolves as we engage with different contexts.
Step-by-step explanation:
When considering words and generativity in language, the statement that is not true is A. Words are lists that we store in our head like a dictionary. Language is not simply a collection of memorized words; rather, our understanding of language relies on a sophisticated set of rules for generating and interpreting speech and writing. These rules are part of our cognitive grammar and include the creation of new words and the pluralization of existing ones, but they also allow for much more complex operations such as composing sentences and conceptualizing abstract thoughts.
From an early age, children demonstrate an understanding of these rules through language acquisition and even through the mistakes they make, such as overgeneralization. For example, children may mistakenly say "gooses" or "mouses" instead of "geese" or "mice," showing their application of the rule for pluralization even when they have not yet learned the exception. This illustrates that our mental lexicon is more than just a stored list; it is a dynamic, rule-based system that evolves and adapts as we encounter different linguistic contexts and cultural norms.
The statement that rules exist for creating words with expletive infixation (C) might be less universally accepted, as it is a more marginal and less regulated aspect of language creativity, yet it still represents an aspect of language generativity and rule application.
