Please explain how to use que,qui, à qui and qu' .....i do not understand

Hi April, your question is a bit too unspecific to be answered by a simple post. Can you be more specific. Maybe reading the corresponding lessons will help you formulate a more specific question?

Bonjour April,
After reading the corresponding lessons as Chris recommended above, here are three other sites that discuss the use of que, qui, à qui and qu'. I do not normally recommend sites outside of Kwiziq but based on your question, I feel that might be of benefit to you. Having said that, after reading the lessons, please repost your question with more specific concerns.

Sometimes when I have difficulty understanding a lesson, I will review other resources for a different perspective on the same topic and that gives me a broader sense of the lesson.

Bonne chance et bonne continuation,
Ron
