illegibility

The word 'illegibility' is a layered construction built upon the core concept of reading. Its foundation is the Latin verb 'legere', which carried the primary meaning "to gather, to choose", and by extension, "to read" as one gathers meaning from symbols. The suffix '-ibilis' was added to form adjectives meaning "able to be", leading to 'legibilis' (able to be read). English adopted this as 'legible'. To negate this quality, the Latin negative prefix 'in-' (meaning "not") was attached, assimilating to 'il-' before the 'l' of 'legible', creating 'illegible'. Finally, the abstract noun-forming suffix '-ity' was appended to 'illegible', resulting in 'illegibility', which denotes the state or quality of not being readable. The word's logic traces a clear path from the ancient act of gathering meaning to the modern frustration of encountering unreadable text.

Structure: il (not) + leg (read) + ibility (quality of being able to be) - il: A Latin prefix meaning "not". It is an assimilated form of 'in-' used before words beginning with 'l'. - leg: From the Latin root 'legere', meaning "to read, to gather, to choose". In this context, it pertains to reading. - ibility: A suffix forming nouns, from Latin '-ibilitas', indicating the quality or state of being able to undergo the action of the verb root. It is a combination of '-ible' (able to be) and '-ity' (state or quality).
