Etymology
The word 'cone' entered English in the 16th century from the Middle French 'cone', which itself derived from the Latin 'conus', meaning a geometric cone or a peak. The Latin term was borrowed from the Greek 'kōnos', signifying a pine cone, a geometric peak, or a spinning top. This Greek origin likely traces back to a Proto-Indo-European root meaning 'to sharpen' or 'a point', a semantic thread that elegantly connects the ancient concept of a sharpened object to the modern geometric shape, the structure of a pine seed, and even the pointed light-sensitive cells in the eye.
Analysis
The word 'cone' is a simplex word borrowed as a whole from Latin. It does not contain separable morphemes in its modern English spelling.
Examples

Colour blindness often results from a defect in one of the three types of cone cells in the eye.
