Final Answer:
Adding the suffix -ity to the adjective "extreme," signifying “exceeding usual limits,” results in a noun, defining the "state that exceeds usual limits."
Step-by-step explanation:
When the suffix -ity is affixed to the adjective "extreme," it transforms the word's grammatical function from an adjective to a noun. The original adjective "extreme" denotes something surpassing typical boundaries or limits. Upon adding the suffix -ity, the word evolves into "extremity," a noun that signifies the state or condition of surpassing usual limits. This change in morphology alters the word's part of speech, transforming it into a noun that represents a state of exceeding ordinary boundaries.
The process of adding suffixes to base words is a fundamental aspect of English morphology. In this case, the addition of -ity creates a noun form that conveys the idea of a state or condition characterized by going beyond the customary boundaries. Understanding these alterations in word structure aids in grasping the nuanced meanings that arise from modifications to base words through affixation, enabling a richer and more precise expression of ideas across different parts of speech.
The transformation of "extreme" to "extremity" showcases the morphological changes that occur when suffixes are applied to words, elucidating how the addition of specific affixes alters the grammatical category and semantic content of the base word, enriching language and facilitating more nuanced communication.
