Keywords Specifying Preposition

Description

A dictionary with preposition expressions. Such expressions often represent a relationship with an adjacent entity. Since most expressions in this dictionary are very short, we require word boundaries (any character other than a letter or number) to appear on either side of the expression. Example expressions include "for", "to", "until", and "in".
