the word 'suggestible' is a modern english formation built upon the verb 'suggest'. the core verb originates from latin suggerere, a compound of sub- ('up from under') and gerere ('to carry, bring'), conveying the literal sense of 'to bring or carry up'. this evolved into the figurative meaning of 'to prompt an idea'. the suffix -ible, also of latin origin, is used to form adjectives meaning 'able to be'. therefore, 'suggestible' literally means 'able to be suggested to', which logically evolved to describe a person whose mind is easily 'carried toward' or influenced by the ideas supplied by others.

Structure: suggest + ible suggest (from latin suggestus, past participle of suggerere meaning 'to bring up, supply, prompt') + ible (from latin -ibilis, an adjective-forming suffix meaning 'capable of, fit for').
