The word "air built" may seem a bit confusing when it comes to its spelling. It is pronounced as /ɛr bɪlt/ in IPA phonetic transcription. The first part, "air," is pronounced as a long "e" sound followed by the letter "r." The second part, "built," is pronounced similarly to the word "tilt," with a short "i" sound followed by the letter "l" and "t." This spelling can be confusing as the "b" is silent and not pronounced like it is in the word "build."
