The expression "gave chair" doesn't make sense because both words are nouns, and using them in that way would not be grammatically correct. However, if we were to consider the verb "give" and the noun "chair" separately, we could explore some synonyms for each word. For "give," some similar words might include donate, contribute, provide or furnish. For "chair," other options could be seat, throne, stool, or bench. Depending on the context and the intended meaning, different synonyms might be more appropriate than others. It's important to choose words carefully to make sure the intended message is communicated clearly.
