self-sufficient

The compound 'self-sufficient' is a relatively modern English formation, combining two ancient roots to express a concept of complete independence. The first element, 'self', has Germanic origins, tracing back to Proto-Germanic selbaz, and embodies the core idea of one's own person or identity. The second element, 'sufficient', enters English via Old French from Latin 'sufficere', which literally means "to put under, to supply." Its components, 'sub-' (under) and 'facere' (to make), suggest the act of providing a foundation from beneath. Therefore, the literal morphemic logic is "making enough from one's own foundation," which evolved into the modern abstract meaning of being capable of meeting one's own needs without external support, encompassing both material and psychological autonomy.

Structure: self (own) + sufficient (enough) self: From Old English 'self', 'seolf', 'sylf', meaning "own, personal, same." It is a pronoun and adjective forming element denoting identity and individuality. sufficient: From Latin 'sufficient-', present participle stem of 'sufficere', meaning "to supply, be adequate." It is composed of 'sub-' (up from under) + 'facere' (to make, do). It functions as an adjective meaning "adequate, enough."
