The spelling of the word "FFING" may seem unusual at first glance, but it is actually based on the pronunciation of the word. The letters "FF" represent a double consonant sound, as in the word "coffee." Meanwhile, the "ING" ending is pronounced with a hard "G" sound, as in "king." Using International Phonetic Alphabet (IPA) symbols, the word "FFING" would be transcribed as /fɪŋ/, with the double "F" indicated as a long "F" symbol.
