nuttier

the adjective "nutty" emerged in the late 18th century, directly from the noun "nut", to describe something containing nuts or resembling them in flavor. by the early 20th century, the slang sense of "crazy" or "eccentric" developed, drawing on the metaphorical association of a "nut" as one's head and the idea of being "off one's nut." the comparative form "nuttier" follows the standard english pattern for forming comparatives, adding the suffix "-er" to the base adjective "nutty," with a connective "i" to maintain phonetic ease. this process illustrates how a concrete noun can evolve into an adjective with both literal and figurative meanings, which then inflects regularly for degree.

Structure: nutt (nut) + i (connective) + er (comparative suffix) "nutt" is derived from the english noun "nut", of old english origin (hnutu). the "i" is a connective vowel often used in adjective formation. "er" is a native english suffix (from old english -ra) used to form the comparative degree of adjectives.
