The word "SENI" has a rather unusual spelling, which can be explained using the International Phonetic Alphabet (IPA). The first three letters, "SEN," are pronounced as /sɛn/, with a short "e" sound and an "n" that is fully pronounced. The final letter, "I," is pronounced as /i/, with a long "ee" sound. Together, the four letters create a word that is pronounced as /sɛni/. While the spelling may seem unconventional, it is still a valid word in certain languages and contexts.
