The words convenance "convenience" and résistance " resistence" are not a prioriin a relation of opposition. However, as their form is similar and their meaning is opposite, they may be conceived by linguistic awareness as antonyms. In his essay Mr Tourrel attempts to reveal whether there is semantic opposition between the words. Proceeding from a lexicographic definition illustrated by examples, he examines wether the two words can be adjusted to the same semantic axis, wether they are in a relation of logical presupposition, and wether they are of opposite semantic value.
