Please anyone suggest some good websites which give tips on the usage of prepositions on a daily or weekly basis.
I have doubts regarding usage of prepositions in many contexts. So wanted to know a general website which would help.
I am a software programmer and i get many doubts regarding the usage of prepsitions many times while discussing on forums.
For example: I am not sure of a sentence like "Is this conference only for android developers or anyone without a prior knowledge of/in android coding can attend? "
