The Vietnamese word "nhát gan" translates to "chicken-hearted" or "weak-hearted" in English. It describes someone who is timid, fearful, or lacks courage. If someone is referred to as "nhát gan," it means they tend to avoid risky situations or challenges because they are afraid.
While "nhát gan" primarily refers to being cowardly or timid, it can also be used more lightly to describe someone who is simply cautious, not necessarily in a negative context.
