Correct spelling for the English word "Sejugous" is [sɛd͡ʒˈuːɡəs], [sɛdʒˈuːɡəs], [s_ɛ_dʒ_ˈuː_ɡ_ə_s] (IPA phonetic alphabet).
I apologize, but "Sejugous" does not appear to have a widely recognized dictionary definition. It is possible that the term is a neologism or a rare, specialized term which does not have an established definition in mainstream dictionaries. It is also worth noting that due to the context-dependent nature of language, definitions can vary across disciplines or groups of people.
If "Sejugous" is a term specific to a particular field or subject, it may have a definition within that context. In order to provide a more accurate definition, it would be helpful to have additional information regarding the field or subject area in which "Sejugous" is being used.
