The word "oligistic" refers to a biological adaptation characterized by a relatively narrow range of environmental conditions that an organism can thrive in. The IPA phonetic transcription of this word is /ɑlɪˈɡɪstɪk/. It is spelled with the prefix "oligo" (meaning "few" or "little") and the suffix "-istic" (meaning "characteristic of" or "relating to"). This spelling accurately reflects the meaning of the word and its pronunciation, with emphasis on the first syllable and a short "i" sound in the second syllable.
