   • Not corrected or made right: "unrectified" describes something that has not been set straight, fixed, or improved after an error, fault, or problem.
   • Not purified or refined: In chemistry, "unrectified" refers to a substance, such as alcohol, that has not been distilled or purified.
   • Not converted from alternating current to direct current: In physics and electrical engineering, "unrectified" describes an alternating current (AC) that has not been converted into direct current (DC) through a rectifier.
   • Not having been straightened or aligned: In geometry or general use, "unrectified" can mean something that has not been made straight or aligned to a correct path.

• General correction:
  • The accountant discovered several unrectified errors in the financial report. (Mistakes that have not been fixed.)
• Chemistry:
  • The laboratory used unrectified alcohol for the initial experiments. (Alcohol that has not been purified through distillation.)

• Geometry/Alignment:
  • The unrectified path of the river caused frequent flooding in the valley. (The river's course had not been straightened or corrected.)

Advanced Usage

• "unrectified error": a mistake that remains uncorrected, often in data processing or accounting.
  • The software flagged several unrectified errors in the database, requiring manual review. (Unfixed mistakes in the data.)
• "unrectified voltage": in electronics, a voltage that alternates between positive and negative values.
