self-indulgence

The word is a modern English compound formed from the reflexive pronoun 'self' and the noun 'indulgence'. 'Indulgence' itself originates from the Latin verb indulgēre, meaning "to be kind or tender towards," and by extension, "to yield to or grant." The prefix in- here serves as an intensifier. Thus, the literal construction implies "yielding excessively to oneself." The concept evolved from the neutral or positive act of granting kindness to a more critical sense of excessive gratification of one's own desires, reflecting a shift in cultural attitudes towards personal discipline and hedonism.

Structure: self (own) + in (in) + dulgence (yielding) self: From Old English self, seolf, meaning "one's own person." It functions as a prefix denoting reference to oneself. in: From Latin in-, a prefix meaning "in, into, on, upon." Here, it intensifies the meaning of the root. dulgence: From Latin dulgentia (indulgence), from indulgēre (to be kind, to yield). The -gence portion represents the noun-forming suffix from the present participle stem.
