a deep divide
chasm - opening
The term ‘chasm’ can be used in both a literal and figurative way. Literally, it describes a very deep and dangerous split or crack in the earth, like that caused by an earthquake. Figuratively, it can be used to express a large division or difference between two or more people, groups, or things. A common mistake that even native English speakers often make with this word is in pronunciation. Despite how it is spelt, it is pronounced ‘ca-zum’.
