Etymology
The word 'sense' entered English in the late 14th century from Old French 'sens', which itself derived from Latin 'sensus', meaning "feeling, perception, meaning." This Latin noun originates from the past participle of the verb 'sentire', "to feel, perceive, think." The ultimate Proto-Indo-European root is believed to be sent-, meaning "to go" or "to head for," which metaphorically extended to the idea of finding one's way or perceiving a direction. This etymological journey illustrates how a concrete concept of physical movement evolved into the abstract faculties of perception, understanding, and meaning.
Analysis
The word 'sense' is a simplex word borrowed as a whole from Latin. It cannot be meaningfully segmented into smaller, independent morphemes using its current English spelling.
