Seme, sememe is a meaningful unit, or more specifically, the smallest meaningful unit. In structural linguistics, seeds are explained in terms of analogies with phonemes. This means that they are units defined in a system of relations, namely the oppositions.
The understanding of meaning is holistic, it places meaning, first and foremost, in language as a system of oppositions, not as individual units in themselves.
