Hi! "Tell" is used when we say who we are talking to: Anna told me that you like films. - What did you tell them? "Say" is used in every other case: Anna said that you like films. - What did you say? You can use "tell somebody" or "say to somebody". I told him to work harder. I said goodbye to him and went home. Hope this helps.

"Say" refers to something that you are speaking or writing without a reference of you are speaking to directly. For example, "I would say that oranges are my favorite fruit." "Tell" refers to you speaking to someone. For example, "I want to tell you a secret."
