This app offers “The Correct Preposition: How to Use It” by Josephine Turck Baker (published in 1911 and currently in public domain).

In English, a preposition can combine with a noun, adjective or verb to form a collocation.

The authors have given a very complete list of common collocations of a noun, adjective or verb with prepositions and detail explanation of how to correctly use prepositions.

In addition, sample sentences are added to illustrate each usage.

Do you know what is the difference between “abound in” and “abound with”?

When do we use “advocate of” instead of “advocate for”?

Do you know which preposition go with adjective “contiguous”?

This app will help you to learn how to choose prepositions correctly.

We hope you enjoy this valuable work.
