The Vietnamese word "sơ giao" is an adjective that means "newly acquainted." It refers to people who have recently met or formed a connection but do not know each other very well yet.
In more advanced contexts, "sơ giao" can be used to discuss the nature of a relationship in terms of its depth and familiarity. For instance, in a business setting, you might say: - Chúng tôi chỉ có một mối quan hệ sơ giao, nhưng hy vọng sẽ phát triển hơn trong tương lai. (We only have a newly acquainted relationship, but I hope it will develop further in the future.)
