"Instratified" is a term used in geology to describe rock formations that have been layered in a unique way. The phonetic transcription of this word is /ɪnˈstrætɪfaɪd/. The prefix "in-" means "not", while "stratified" refers to layers. By combining these two parts, we get the meaning of "not layered", which is contradictory to the actual definition of the word. The spelling of this word can be tricky and requires a solid understanding of prefixes, suffixes, and root words.
