The correct spelling of the word is "between" /bɪˈtwiːn/. The IPA phonetic transcription shows that the word consists of two syllables with the primary stress on the second syllable. The "t" and "w" sounds blend together to form a single consonant sound "tw". This is further followed by the long "e" sound, represented by the vowel symbol "i" with a horizontal bar above it. The spelling "betwee" is incorrect and will likely result in confusion or misinterpretation.
