The correct spelling of the word is "Shending" with a schwa sound in the first syllable. It is pronounced /ʃəndɪŋ/. The "sh" sound is represented by the letter "s" and an "h" coming together, and the "e" after it represents the schwa sound. The second syllable "ding" is pronounced with a short "i" sound followed by a "ng" sound. Correct spelling is important to ensure clear communication and understanding of the intended meaning of words.
