Etymology
the word 'capping' is built upon the root 'cap', which traces its lineage to the latin 'caput', meaning 'head'. this core concept of a head, as the topmost part of the body, evolved metaphorically to signify any top, cover, or limit. the addition of the old english agentive or gerundial suffix '-ing' transforms the action into a noun, denoting the process or result of applying such a cover or limit. thus, the modern term logically extends from the literal idea of placing a head or top on something to the more abstract concepts of imposing a ceiling or finalizing a structure.
