Big, large; of people also old or older in age. As a predicate it normally takes 很: 这个很大 'this one is big'. Age is asked as 'how big': 你多大? 'how old are you?'. Rain, wind and sound are 大 too: 雨很大 'it is raining hard'. Its opposite is 小.
To, lớn; nói về người thì còn chỉ tuổi tác (lớn tuổi, lớn hơn). Làm vị ngữ thường có 很: 这个很大 (cái này rất to). Hỏi tuổi cũng dùng chữ này: 你多大？ (bạn bao nhiêu tuổi?). Mưa, gió, tiếng động cũng nói 大: 雨很大 (mưa to). Trái nghĩa là 小.
