 Hi students, it's Shayna from espressoenglish.net and the expression I want to teach you today is deep down. If you feel an emotion, deep down, this means you feel it strongly inside your heart, but you don't admit it or let it show to other people. For example, Rachel seemed very happy and successful, but deep down she was miserable. So again, this expression refers to hidden emotions which you feel inside your heart but you don't make it obvious to other people and maybe it's not even obvious to yourself. Thanks for joining me for another Phrase of the Day and I'll see you in the next video.
