Best practice
When using "per time", ensure the context clearly defines what constitutes a 'time'. This enhances clarity and prevents ambiguity.
Common error
Avoid using "per time" when a more specific term like "per day", "per week", or "per event" would provide better clarity. Vague use can confuse the reader.

Ludwig's WRAP-UP
In summary, while grammatically correct, the phrase "per time" is not commonly used in modern English. Ludwig AI acknowledges its validity but suggests that alternative expressions like "each time" or more specific frequency indicators (e.g., "per day", "per week") are often preferred for clarity and better understanding. When writing, consider whether "per time" effectively conveys your intended meaning or if a more precise term would enhance your message. Always strive for clarity to ensure your audience understands your communication. "Per time" can be used, but with consideration.

FAQs
How can I use "per time" in a sentence?
What's a good substitute for "per time"?
Depending on the context, you could replace "per time" with "each time", "every time", or "for each instance".
Is it better to say "per time" or "each time"?
"Each time" is often preferred over "per time" because it is more common and easily understood. "Per time" can sound awkward to some native English speakers. For example, instead of "It rained two inches per time", write "It rained two inches "each time" it rained".
What is the difference between "per time" and "at a time"?
"Per time" implies a rate or frequency, while "at a time" refers to the quantity or amount taken during a single instance. Use "per time" to indicate how often something happens and "at a time" to describe how much is involved "in one go".
