"Clift" is a specific term used to refer to a narrow passage or a deep narrow ravine, typically formed by water. However, there are several synonyms that can be used instead of "clift" to mean a similar idea. These include gully, chasm, canyon, crevasse, gorge, fissure, ravine, and defile. Each of these words carries a slightly different connotation, but they all refer to a narrow, steep-sided valley or passage. Some words, like canyon and gorge, imply greater depth and geographical extent, while others, like fissure and crevasse, suggest a smaller and narrower opening.
