How Do You Spell COVERINGED?
Pronunciation: [kˈʌvəɹˌɪnd͡ʒd] (IPA) 
The spelling of the word "coveringed" seems odd and may leave you scratching your head. However, looking at its phonetic transcription in IPA (kʌvərɪŋd), we can understand why it is spelled this way. The "-ed" suffix is added to "covering," but the final syllable's stress changes from the first syllable to the second, resulting in dropping the "e" in "covering" and doubling the final consonant "g." Thus, resulting in "coveringed." It may seem strange, but it's just another example of English's quirky spelling rules.
