The spelling of the word "daffier" may seem peculiar, but it follows standard English phonetic rules. Phonetically, this word is transcribed as /ˈdæfɪər/. The "a" in the first syllable is pronounced as a short "a" sound, while the "i" in the second syllable is pronounced as a long "e" sound. The "er" at the end represents the comparative form of the adjective, meaning more daffy or crazy than something else. While this may not be a commonly used word, its spelling follows the general pattern of English pronunciation.
The word "daffier" is derived from the adjective "daffy". The term "daffy" originated in the early 19th century, and it is believed to be a variation of the word "doff", which means to remove or take off. In this context, "daffy" initially referred to someone who was off their head or acting strangely, as if they had removed their own hat, figuratively speaking. The suffix "-ier" is added to create the comparative form, giving us "daffier", which means more daffy or crazier.
