A travel video blogger’s video contained a brief shot of a can of Sprite, labelled in hangeul as 스프라이트 (seu-peu-ra-i-teu). So one syllable of English becomes five syllable blocks (jamo) of hangeul. There are three reasons for this.
The first is that the phonotactics of Korean do not allow for initial consonant clusters. The s and p must be extracted to their own syllable, completed with the most neutral vowel ㅡ (eu). This is not quite as reduced as the English schwa, but performs many of the same tasks.
The second is that there is no single letter corresponding to the English vowel in Sprite, but it can be approximated by using ㅏ and ㅣ. Compare the IPA symbol /aɪ/, which clearly shows that the English vowel is a diphthong. I know of two Korean words which use this combination of vowels: 아이 (a-i, child) and 아이고 (a-i-go, approximately ‘gosh!’, most often used by middle-aged women).
The third is that only a few consonants can occur at the end of a syllable. While ㅌ occurs at the end of 밑 (mit, bottom), this is rare, and as far as I know is never used in transliterations of English words. So the t must also be extracted to its own syllable. Whenever you see a long string of Korean syllables, with the first and last containing ㅡ, it is almost certainly a transliteration of an English word. Some common English loanwords are 스트레스 (seu-teu-re-seu, stress) and 스포츠 (seu-po-cheu, sport(s)).
I can’t remember seeing Sprite in Korea; the ubiquitous soft drink is Chilsung cider.
There is considerable variation in the names for carbonated soft drinks in English. To me, in standard Australian English, the neutral/slightly lemony drink is lemonade, the distinctly lemony drink is lemon squash or squash (sometimes with real lemon (which might be called traditional lemonade, sometimes only with flavouring), and cider is apple unless otherwise specified (eg pear cider). Other terms include soda, soda pop, pop, coke and cola. There is also soda water, which I would categorise separately. Koreans also use ade and chino either by themselves or attached to part of other drinks.
