COMMON If a statement or promise rings hollow or sounds hollow, it does not seem true or sincere. Now the promise of a long, secure career rings hollow, employers must find new ways to attract staff. Official claims that the two countries are close friends sound increasingly hollow. Note: You can also say that a statement or promise has a hollow ring. The Government's claim to be making record investments in railways has a very hollow ring. Compare with ring true. Note: The idea is of an object that is meant to be solid making a loud noise when struck, indicating that it is weaker or cheaper than it was believed to be.
