Key Differences
"So" is used primarily to intensify adjectives and adverbs, adding emphasis to their qualities. For example, when someone says, "The movie was so interesting," "so" enhances the adjective "interesting." On the other hand, "such" is used to amplify the characteristics of nouns or noun phrases, as in "It was such an interesting movie," where "such" emphasizes the whole noun phrase "an interesting movie."
While "so" often leads into an effect or result with constructions like "so... that," as in "so hot that I couldn't stay outside," "such" does not typically connect directly to a result but rather emphasizes the exceptional nature of the noun phrase, as in "such hot weather." This difference influences how each word fits into sentence construction and the type of emphasis they provide.
"So" can be used in simpler constructions to quickly add intensity, making it suitable for casual speech and straightforward statements. Conversely, "such" is slightly more formal or emphatic and is preferred in written English or more elaborate expressions.
In the context of expressing large quantities or degrees, "so" often appears with "many" or "much," like "so many people" or "so much noise." Meanwhile, "such" fits directly before a noun or a noun with an adjective, enhancing the impression of the noun's extent or quality, as in "such noise" or "such a big crowd."
Both "so" and "such" serve to intensify statements, "so" focuses more on modifying adjectives and adverbs, and "such" targets noun phrases, each shaping the emphasis in different yet effective ways.
