The word "backet" is misspelled. The correct spelling is "bucket," pronounced /ˈbʌkɪt/. The phonetic transcription shows that the initial sound is a voiced bilabial stop /b/. The vowel sound is a short u /ʌ/, followed by a consonant cluster /kɪt/ consisting of a voiceless velar plosive /k/ and a voiced alveolar stop /t/. Therefore, the correct spelling and phonetic transcription of this word is "bucket" /ˈbʌkɪt/.
In a kitchen, a wooden or iron vessel for carrying coal or ash.
