Sema is a differential semantic attribute, a component of meaning, which is revealed by comparing the meanings of different words . It is an indivisible component of the lexical meaning ( sememe ).
For example: the words good - bad differ by the seed of denial.
The procedure for isolating sem in the meaning of words is called component analysis and is carried out by building binary opposites .
The ideographic dictionary contains seme as units.
