The word 'suggestibility' is a modern psychological term constructed from the verb 'suggest' and the abstract noun suffix '-ibility'. Its core, 'suggest', originates from the Latin suggerere, a compound of sub- ('up from under') and gerere ('to carry, bring'), literally meaning 'to bring or carry up', which evolved to mean 'to offer an idea, to hint'. The suffix '-ibility', a variant of '-ability', derives from Latin -abilitas, which itself combines the verb-forming suffix -abilis ('able to be') with the abstract noun suffix -tas ('state of'). Thus, the literal construction 'state of being able to be suggested' elegantly captures the modern abstract meaning: a person's inherent susceptibility to having ideas implanted or to being influenced by external propositions.
