The Vietnamese word "kẽ nách" refers to the space or area between two things, often used to describe the gap or space between the body and the arm, commonly known as the "armpit" in English. However, in a more figurative sense, it can also describe a neighbor who lives very close to you, akin to someone who is "just next door."
In more advanced conversations, "kẽ nách" can be used to express the idea of closeness in a community or neighborhood. For example: - "Chúng tôi thường tổ chức tiệc tại nhà người kẽ nách để gắn kết tình hàng xóm." (We often host parties at our next-door neighbor's house to strengthen neighborly bonds.)
While "kẽ nách" primarily refers to the armpit or a neighbor, in some contexts, it can also imply a close relationship or connection between people, much like how neighbors often have close interactions.
