The ability to speak well is the hero’s primary quality in Cyrano de Bergerac. It is no coincidence that his other obvious talent is swordplay; although, it is noteworthy here that witty banter is often equated with dueling in this play, as characters slash at one another with words. Love is also defined largely by language and only seen as valid when accompanied by long, eloquent poetic descriptions. A simple "I love you" will not do in this play, but sonnets about Venus will make a woman melt.
To his death, Cyrano values his words above all else.
Despite his talent with words, Cyrano loses his faith in words when he is forced to speak through Christian; he comes to see language as a vehicle for deception and mere artifice.
