Lecture semantic classification of words

Synonymic dominant is the most frequently used neutral word within a synonymic group (as look in the row look, watch, gaze, stare, glance).
Antonyms are two words belonging to the same part of speech and their denotational meanings express contrary or contradictory notions (opposite meanings).
Contradictories are antonyms that represent the type of semantic relations that exist between pairs like ‘dead’ and ‘alive’, ‘single’ and ‘married’, ‘perfect’ and ‘imperfect’, etc. We can easily distinguish this group of antonyms from the other groups by means of using ‘not’ before one of the member of the pair to make them semantically equivalent to each other, e.g. cf. not dead = alive, not single = married. ‘
Contraries are antonyms which admit such possibilities. This may be observed in ‘cold — hot’, because we have ‘cool’ and ‘warm’ as intermediate members.
