The expression "be lost for words" means to be unable to find the right words to express oneself. We use this expression when we are feeling overwhelmed, surprised or moved in some way that makes it difficult to communicate effectively. For example, if someone gives you a really special gift or tells you something incredibly amazing, you might be so overwhelmed that you can't find words to say how you feel. In that case, you could say "I'm lost for words" to express your emotions.
