This volume aims to provide information about

and interpretations of the concept of evidentiality

lexically realized with certain verbs and

applied to the genre of medical posters. More

specifically, issues relating to how knowledge

is conveyed through language will be discussed

and how evidence for such knowledge is linguistically

transmitted in a set of specialised texts.

This study uses some of the possibilities offered

by electronic corpora in conjunction with concordance

tools, which allow quantitative analysis.

Thanks to this quantitative analysis, followed

by a qualitative interpretation of the

findings, we could detect the pragmatic function

these evidential items have in contextual use,

allowing us to see that evidentiality in medical

discourse is intended in a slightly different way

from general discourse.
