How Do You Spell BRENNINGLY?
Pronunciation: [bɹˈɛnɪŋlɪ] (IPA) 
The word "Brenningly" is spelled with two N's, despite the fact that it is pronounced with only one. This is because the pronunciation of the word is influenced by a phenomenon known as gemination, in which consonants are duplicated in certain contexts. In IPA transcription, the word is represented as /bɹɛnɪŋɡli/, with the doubled N represented by the symbol ŋ. This spelling rule applies to other words as well, such as "planning" and "running".
