Synonym discussion

Sense: adjective/1

All four words describe a person whose feelings are easily hurt, but they differ in tone and scope. 'Sensitive' is the most neutral and common — it can describe both emotional reactivity (sense 1) and desirable empathy (sense 3). 'Touchy' is informal and suggests quickness to anger or irritation about a specific subject: He is touchy about his height. 'Thin-skinned' is conversational and vivid, implying that criticism penetrates too easily: A politician cannot afford to be thin-skinned. 'Vulnerable' is broader and gentler; it describes a person in a fragile emotional state rather than a fixed personality trait: After losing her job, she felt vulnerable to any negative feedback. Use 'sensitive' for general emotional reactivity, 'touchy' for defensiveness about a specific topic, and 'vulnerable' when the person is going through a difficult period.

Etymology

LatinFrenchEnglish

The word 'sensitive' traces back to the Latin verb 'sentire', meaning 'to feel' or 'to perceive'. From this came the adjective 'sensitīvus' ('capable of feeling'), which passed through French 'sensitif' before entering English in the late 1300s. The original English meaning was simply 'having the power of sensation' — a physical capacity. Over time, the meaning expanded to include emotional sensitivity (first recorded around 1600), and later in the 1800s the sense of 'requiring careful handling' and 'high-precision measurement' developed as the word was applied to social situations and then to scientific instruments.
