## AI Etymology
Unseeable comes from un- ('not') + seeable, from see, from Old English sēon ('to see'), from Proto-Germanic *sehwaną. In current use it is an adjective meaning "impossible to see; invisible". That sense is explained by the older material without requiring a speculative semantic step: the inherited or borrowed base supplies the field of meaning, while the English formation fixes its modern role. The prefix un- is negative or privative, marking the absence, denial, or opposite of the base idea. The surface form is compositional: its joined elements remain visible in the modern word. The historical chain includes Old English un-, Old English sēon, and Proto-Germanic *sehwaną. Related English forms include see, seeable, unseen, and unseeing. As a result, the modern word is best read as a negative, privative, or reversative formation built on a historically older base.
