The use of expressions in the technical or specialized language is not restricted to one specific field. Many expressions and terms that arise in a specific field of knowledge then are taken by another one. Even most of the specialised languages come from the general language. This happens because language is not a closed system. For that reason, words have more than one meaning and can be used in different contexts.
In this article, I want to talk about three verbs that usually go with the noun illness making up collocations. These verbs are develop, have, and suffer. The aim is not to evaluate the correctness of each collocation, but to distinguish the contexts in which they are used within the field of medicine.
