Tip of the Tongue
Have you ever thought of something but you couldn`t remember the specific name for it? For example, if I just watched a movie last weekend and my friend asks me what the title was but I can only remember what happened in the movie. I think to myself that I definitely know the title but for some reason I can not remember it at that moment. In America, some people say, " the answer is at the tip of my toungue," which means they understand what you are talking about but can not remember the specific title, date or information related to the topic.
I hope everyone has a great day!
