Expert writing Tips

Best practice

When aiming to describe the relationship between a data point and its index, ensure you use the correct term "indexed by" or "indexed with" to clarify that the data point is being found via index.

Common error

Many writers mistakenly use "index with" when they mean "indexed with". Remember, "index" is the noun (the listing), and "indexed" is the verb (the action of creating the index). For instance, use "The database is indexed with keywords", not "index with".
