attainable

the word 'attainable' is built upon the verb 'attain', which entered english from old french 'ataindre', itself derived from the latin verb 'attingere' (ad- 'to' + tangere 'to touch'). the core concept of reaching or touching a point evolved into the abstract sense of achieving a goal or state. the suffix '-able', of latin origin via french, is productively added to verbs to form adjectives indicating possibility or capability. thus, 'attainable' literally means 'capable of being reached or achieved', a meaning that has remained consistent from its formation to modern usage.

Structure: attain + able attain (from latin 'attingere', meaning to reach, touch, or arrive at) + able (from latin '-abilis', a suffix forming adjectives meaning 'capable of, fit for').
