Etymology
The word 'cap' traces its lineage to Late Latin 'cappa', a term for a hood or cape. This Latin word is likely derived from 'caput', meaning 'head', emphasizing its primary association with the head. The semantic journey saw the meaning narrow from a general head-covering garment to specifically denote a brimless hat. The verb senses, such as to cover or to top, developed naturally from the noun's core concept of being a covering for an extremity, whether on the head or on an object.
Analysis
The word 'cap' is a simplex word. It is a borrowing from Late Latin 'cappa', meaning a hooded cloak or head-covering. Its functional role is as a complete lexical root.
