How do you say 'timelord' in Latin?

There is no direct translation for the word Timelord from English to Latin because the word did not exist at the time the Latin language was created.

We can, however, take the portmanteau of Timelord, and separate it into its component words and translate that.

The literal translation of "Time Lord" from English to Latin is "Tempore Dominus."

The Timelord character is a product of the BBC's Doctor Who television series. The series first aired on November 23, 1963, airing until December 6, 1989.

The series was brought back in 2005 and has reached its 7th season which premiered on December 25, 2011, starring Matt Smith (born Matthew Robert Smith on October 28, 1982 in Northampton, Northamptonshire, England) as the eleventh Doctor.
