Hello, I hope everyone is in good health😊 I often get bewildered regarding “which” and “that” I don't know what to put here. 1- I have found the pen “which/that” I lost. 2- Here is the book “that/which” you lent me. 3- please suggest dictionary “which/that” includes phrasal verbs and idioms. 4- This is the house “which/that” belongs to my uncle.
