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.
