The Vietnamese word "chật chội" is an adjective that means "cramped" or "crowded." It describes a situation where there is not enough space, making it uncomfortable for people or things. You can think of it as a place where you feel tight or squeezed because there are too many items or people in a small area.
Nhà của chúng tôi rất chật chội.
(Our house is very cramped.)
Trong xe buýt đông người, tôi cảm thấy chật chội.
(I feel cramped in the crowded bus.)
While "chật chội" primarily refers to a lack of space, it can imply discomfort or a feeling of being overwhelmed in a crowded situation.
