The Vietnamese word "phều phào" can be translated to English as "sputter weakly." It describes a way of speaking or expressing oneself that lacks strength or clarity. This term is often used to convey a sense of frailty, exhaustion, or a lack of confidence in one's words.
"Phều phào" can also be used metaphorically to describe a situation where someone is not expressing their thoughts clearly or assertively. For example, in a discussion or debate, if someone is hesitant or unsure, you might say they are speaking "phều phào."
While "phều phào" primarily refers to weak speech, it can also be used to describe someone who is in a weak physical state, such as being unwell or fatigued.
