"你更脆弱" 的英文表达可以是 "You are more vulnerable"。
"Vulnerable" 是形容词，意思是易受伤害或受影响的，有时指身体脆弱，有时指情感脆弱。例如：
"Children and the elderly are often more vulnerable to illness."（儿童和老年人往往更易生病。）
"After her divorce, she felt vulnerable and struggled with low self-esteem."（离婚后，她感到脆弱，自尊心低落。）
"Vulnerable" 源于拉丁语 "vulnus"，意思是伤口或伤害。它进入英语后逐渐演变为指人易受伤害的意思。
