The aim of this contribution is to provide lines of thought about some concepts involved in making sens by individual, when him represents the real-life urbanspace. Cognitive and semantic process takes place through sensory experience which the individual has in the space, from the multi-sensory perception of it. The individual is an agent since his experience, of and in the space, is connected to hisactions and practices. The image of the city which ensues from it, then proceeds at the same time of the interpretation of the materiality of the city (spatial identity) and the way the agent gets in touch with the space and with others (individual and/or shared identity). Habitus, practices, capitalization of past experiences, sensory perception, expectations, spatio-temporal context, ... are so many elements influencing the sens making process which underlies thechoices of actions. Understanding the dynamic process of urban spaces semantization, allows to seize better the current manners to appropriate evolving spaces, in spatial and social and cultural way.
