How do I use COD and COI in French? I need to know how and where I need to add the le/la/l' in sentences. Also where I need to add lui/leur ? What are the things I need to understand to use them?​

Le is used for a masculine word, La is used for a feminine word, and L' is used in a situation where the first letter of the next word is a vowel. (eg. "the education" ; "l'éducation"). Sorry, Im not sure about COD and COI </3

Lui is used for a singular person, and Leur is for plural. They're used for indirect responses and are used after "à"
