In Vietnamese, comparative adverbs are a crucial part of the language. They are used to compare the similarities or differences between two things, situations, people, etc. Vietnamese comparative adverbs are formed by adding the words ‘hơn’, ‘bằng’, or ‘kém’ after adjectives or other adverbs. For example, “nhanh hơn” (faster), “khéo léo hơn” (more skillfully), “dễ bằng” (as easy as), “khó kém” (less difficult). These comparative adverbs are vastly used in everyday conversation and written language.
