Cadit quaestio
From Wikipedia, the free encyclopedia
Cadit quaestio, Latin for "the question falls," is a legal term used to indicate that a settlement to a dispute or issue has been reached, and is now resolved. In English, there is a similar idiom when people say that "the shoe has dropped."
In journalism, the abbreviation "CQ" is used to indicate that a fact, such as the spelling of a name, has been checked and found to be correct.
Cadit is the third person singular indicative active of the irregular Latin verb cado and quaestio is the nominative singular form of a third declension noun. These two words, together, form a sentence complete unto itself.
