Etymology

Origin of vulnerable

First recorded in 1610–20; from Late Latin vulnerābilis “injurious, wounding,” equivalent to Latin vulnerā(re) “to wound” + -bilis; see -ble

Explanation

Use the adjective vulnerable to describe something or someone open to being physically or emotionally wounded, like a newborn chick or an overly sensitive teenager. Vulnerable is from Latin and is based on vulnus, "wound." From its literal meaning, it has come to be more often used for someone who is easily hurt or likely to succumb to temptation. It's best used for a person whose feelings are so delicate that they can't withstand any criticism or pressure: "Don't speak harshly to her, she's very vulnerable today."
