The word "sible" is not a commonly used word in English, and it can be confusing to spell due to its unusual pronunciation. In IPA phonetic transcription, it is spelled /ˈsɪbl/, with the stress on the first syllable. This word is derived from the Latin word "sibilare," which means "to hiss" or "to whisper." While this word may not be encountered often in regular usage, it is helpful to understand its spelling and origin.
