Definition

Adverb: * Up to that time; until that point in the past. It refers to a period leading up to a specific time or event that has just been mentioned or is about to be mentioned. It is a formal and somewhat archaic word.

Usage

• Position in Sentence: Typically used in the middle or toward the end of a clause.
• Context: Used to describe a state, condition, or action that was true or ongoing a particular past moment. It often contrasts with a change that happened at that moment.
• Register: This word is very formal and is most commonly found in legal, historical, or academic writing. In everyday speech, phrases like "until then," "up to that time," or "previously" are used instead.

Examples

• The law, which had theretofore been ignored, was suddenly enforced with great severity.
• She discovered evidence that proved his theretofore unquestioned honesty was a fabrication.
• The company's profits, stable theretofore, began to decline sharply after the new regulations.

Advanced Usage

• Contrast with 'Thereafter': "Theretofore" looks backward from a past point (up until then). Its counterpart "thereafter" looks forward from a past point (after then).
  • The treaty was signed in 1995. Theretofore, the region had been in conflict. Thereafter, a period of peace began.
