The Vietnamese word "thầm" is an adjective that primarily means "secret" or "quiet." It describes something that is done in a hidden or discreet manner.
You can use "thầm" to describe actions, feelings, or thoughts that are not openly expressed or that are kept hidden from others.
In a more literary or poetic context, "thầm" can also express deep emotions or thoughts that are kept inside, not just in a physical sense of secrecy.
While "thầm" generally implies secrecy or quietness, in some contexts, it can also convey a sense of intimacy or personal reflection.
