In Afrikaans grammar, comparative adverbs are used to compare two or more actions, situations, or qualities. They are formed by adding the suffix “-er” to the original adverb, or by using “meer” (more) before the adverb. Additionally, the word “as” (than) is often used to make comparisons between two things. It’s important to practice forming and using comparative adverbs in Afrikaans to better understand the language structure and improve your communication skills.
