impressionable

the word impressionable is built upon the latin verb imprimere, meaning 'to press into'. this literal action evolved metaphorically; just as a seal leaves a physical mark in wax, experiences can leave a mental or emotional mark on a person. the suffix -ion turns the action into the noun 'impression', denoting the mark or effect made. finally, the suffix -able attaches, creating an adjective that describes someone or something 'capable of receiving an impression'. thus, the modern meaning logically extends from the physical concept of being soft enough to be marked to the psychological state of being susceptible to influence.
