The Vietnamese word "sì" is an adverb that means "very," "excessively," or "extremely." It is used to emphasize the degree or intensity of an action or quality.
Sì đẹp: Very beautiful
Sì nhanh: Extremely fast
In more advanced contexts, "sì" can be used to express strong opinions or emotions. For example: - Sì buồn: Extremely sad - Hôm nay tôi cảm thấy sì buồn. (Today I feel extremely sad.)
While "sì" primarily means "very" or "extremely," in certain dialects or contexts, it can also be used to express a sense of annoyance or frustration. However, this usage is less common and can vary by region.
