47+ Synonyms of Vulnerable: From Exposed to Susceptible

Using “vulnerable” repeatedly can make your writing feel repetitive, but choosing the wrong replacement can change the meaning. The right synonyms of vulnerable depend on the type of vulnerability you mean. If someone lacks protection, defenseless, unprotected, exposed, or unguarded may fit. If something is easily affected by a particular risk, susceptible, prone, or at risk can be more precise. For emotional vulnerability, sensitive, open, or emotionally exposed may work better.

These alternatives are related, but they are not interchangeable in every sentence.
