The spelling of the word "segub" can be explained through the use of IPA phonetics. In IPA, the word would be transcribed as /sɛɡʌb/ with the "s" pronounced as "ess," the "e" as in "bet," the "g" as in "go," the "u" as in "but," and the "b" as in "bat." The word may not be familiar to some English speakers, but proper use of IPA can aid in accurate spelling and pronunciation.
