SELF (O.Eng. seolf, silf, &c., cf. Dutch zelf, Ger. selbe, selbst), as a pronoun, an element attached to a personal pronoun or pronominal adjective to give emphasis, or to indicate a reflexive use; as an adjective a word properly meaning same, identical, also very (seen in the expression “self-same”), hence single, plain, not mixed with another colour. It is also a florist's term for a flower which has uniformity of tint, without markings or other tints. As a noun “self” means one's own person; for the psychological use of the term see Psychology, &c., and for its ethical aspect Egoism.
