The spelling of the word "Teytin" may seem unusual, but it can be explained using the International Phonetic Alphabet (IPA) transcription. The first sound is the "t" sound, followed by the diphthong "eɪ" which represents the "ay" sound in "hay". The next sound is the "t" sound again, followed by the "ɪ" or "ih" sound in "sit", and finally the "n" sound. So, the correct pronunciation of "Teytin" is "Tay-teen".
