Etymology
The word is a modern English compound formed from three distinct elements. The core concept originates from the Latin verb 'claudere' (to shut), which passed into Old French as 'clos' and entered English as 'close'. The prefix 'en-', from Latin 'in-', was added to form the verb 'enclose', meaning to shut in or surround. The final and most recent layer is the addition of the Old English reflexive pronoun 'self', which intensifies the meaning to imply complete internal containment or autonomy. Thus, the literal progression from 'shut' to 'shut in' to 'shut in by itself' clearly illustrates the evolution into its modern senses of being physically sealed off or functionally independent.
Analysis
Structure: self + en + closed
self: (Old English) A pronoun meaning 'one's own person'. In this compound, it functions as an intensifier meaning 'by or of itself'.
en: (Old French, from Latin) A prefix meaning 'in, into, within, on'. Here, it functions as a verb-forming prefix attached to the adjective 'closed'.
closed: (Past participle of 'close', from Old French, from Latin) Meaning 'shut, confined, not open'. It functions as the core adjectival element describing the state.
