The Vietnamese word "sân bóng" is a noun that means "football ground" or "football pitch." It refers to the area where football (soccer) is played.
You can use "sân bóng" when talking about places where football is played or when discussing football matches. It can be used in both casual conversations and more formal discussions about sports.
In more advanced contexts, "sân bóng" can be used in discussions about facilities for football, such as the quality of the pitch, the type of grass used, or the arrangement of the field for tournaments.
While "sân bóng" primarily refers to a football pitch, in some contexts, it can refer to other types of pitches or fields used for different sports, although this is less common.
