The correct spelling of the phrase "study at qualm" is somewhat challenging for non-native speakers of English. The first vowel sound in "qualm" is pronounced as a diphthong, meaning that it consists of two distinct sounds. In IPA phonetic transcription, the word is written as /kwɑm/. The "kw" represents the consonant cluster at the beginning of the word, while the "ɑ" and "m" represent the two distinct vowel sounds in the word. This is an important aspect of proper spelling and pronunciation for anyone studying English as a foreign language.
