[doun-too-urth, -tuh-] 
| practical and realistic: a down-to-earth person. |
down to earth
Back to reality. For example, It's time the employees were brought down to earth concerning the budget. P.G. Wodehouse had this idiom in Very Good, Jeeves! (1930): "I had for some little time been living . . . in another world. I now came down to earth with a bang." [Late 1920s]
Also, down-to-earth. Realistic or interested in everyday occurrences, as in She is a very down-to-earth person, not at all involved with the glamour of Hollywood. [1930s]
