Our bodies give us so many expressions . And today we talk about the facial feature that sticks out the most…your nose ! Well , unless you are wearing a mask , which covers the mouth and nose . But most of the time our noses are noticeable . You can see them clearly . And that fact gives us this expression : “as plain as the nose on your face .” This describes something that is very clear , easy to see or understand . It is obvious . Here is one way to use it . My friend Marina liked my other friend , Christopher , a lot . She never told me , but I could tell . Every time he entered the room she acted differently . She talked faster and fixed her hair a lot . And she laughed at every joke he made , even the ones that were not funny . So , to me she obviously liked him . When I asked her about it , she said , “How did you know ?” “Marina , I said , "it's as plain as the nose on your face . Her face turned deep red from embarrassment . Imagine we all have to wear masks all the time for years and years . If that happens , this expression might change . But for now we still use it . Here is our next expression . It's an easy one : on the nose . This expression has two very common meanings . If something is “on the nose ,” it is exactly right . It is accurate . For example , his guess about the new company succeeding was right on the nose . After only a year , it is making a lot of money . “On the nose ” also means something happens at the exact set time . And she arrives to the office every day at 10am on the nose . But being “on the nose ” and on time doesn't mean you have to do it every day . It just means you agreed to be somewhere at a certain time and you are there . Some word experts say this usage of “on the nose ” comes from radio . When recording a radio show , the voice performers are in a recording room . They are separated from the producers and sound experts by glass . Oftentimes , the recording could not be interrupted . So , if a show was running on time , the producer would put a finger on his or her nose to let the performers know . Here is our last expression . One thing noses do is smell things . The nose can help us find food . This is a valuable ability . So , if you have a special ability for something , we can say you “have a nose ” for it . For example , a good detective has a nose for solving crimes . They can sniff out hidden clues . If you have a nose for news , you are good at finding news stories . It's like you can sniff out an interesting story . Many of our listeners definitely have a nose for learning English .
