Expert writing Tips
Best practice
When describing past practices, ensure the verb tenses are grammatically correct. Use "used to" for habits and "were used" for passive constructions indicating purpose. For example, instead of saying "use were used to", say either "they used to use" or "the tools were used to...".
Common error
Avoid blending the expressions "used to" (for past habits) and "were used to" (passive voice). A common error is phrases like "use were used to," which mixes these structures incorrectly. Always separate the concepts: use "used to" to describe something someone did regularly in the past, and "were used" to describe the purpose of something.
