At the heart of natural language processing is the understanding of co
ntext dependent meanings. This paper presents a preliminary model of f
ormal contexts based on situation theory. It also gives a worked-out e
xample to show the use of contexts in lifting, i.e., how propositions
holding in a particular context transform when they are moved to anoth
er context. This is useful in NLP applications where preserving meanin
g is a desideratum.
