"Gaddy" is not a commonly used term, but it is typically spelled with two "d"s. Its pronunciation is /ˈɡædi/, with the first syllable emphasized and a short "a" sound. The letter "g" is pronounced like "guh," while the "a" sound makes a brief, indistinct vowel in the middle. The double "d" consonants make for a sharp, hard stop at the end of the word. Despite being an infrequently used term, the phonetic spelling of "gaddy" is straightforward and simple to understand.
