In this contribution the author shows that the metaphorical scope of the sense of smell is not weaker than that of other perception domains like hearing or vision. Apart from the two mappings proposed by Sweetser, namely the indication and detection of dislikeable characteristics, she identifies other metaphorical extensions like 'to guess', 'to suspect' and 'to investigate', as well as physical semantic extensions like 'to trail something'. These semantic extensions are not restricted to one language but common to the three languages examined, namely English, Basque and Spanish. All the possible extended meanings that these verbs can convey can be explained with 'property selection processes', i.e. the selection of some properties from the set of prototypical properties that characterize the sense of smell.
