A sememe is a proposed unit of transmitted or intended meaning; it is atomic or indivisible. A sememe can be the meaning expressed by a morpheme, such as the English pluralizing morpheme -s, which carries the sememic feature [+ plural]. Alternatively, a single sememe (for example [go] or [move]) can be conceived as the abstract representation of such verbs as skate, roll, jump, slide, turn, or boogie. It can be thought of as the semantic counterpart to any of the following: a meme in a culture, a gene in a genetic make-up, or an atom (or, more specifically, an elementary particle) in a substance. A seme is the name for the smallest unit of meaning recognized in semantics, referring to a single characteristic of a sememe.
- Denotational 1: Primary denotation, for example "head" (body);
- Denotational 2: Secondary denotation by resemblance with other denotation: "head" (ship);
- Connotational 1: High position, as the role or function of "head" in the operation of the human body;
- Connotational 2: Emotive, e.g., meaning in "honey";
- Connotational 3: Evaluative, e.g., meaning in "sneak" – move silently and secretly for a bad purpose
The operational definition of synonymy depends on the distinctions between these classes of sememes. For example, the differentiation between what some academics call cognitive synonyms and near-synonyms depends on these differences.
