Besides the social code and its conditions, communication is inseparable of a particular situation. The same words can be refered to different objects depending on the circumstances, the involved subjects, a logic situation. According to Bourdieu, the strict meaning of words is rarely used, "product of the neutralization of the practical relations in which it works, the word of the dictionary does not have any social existence: in practice, it only exists plunged in situations…."
