Expert writing Tips

Best practice

When using "source of", ensure that the noun following "of" clearly identifies what is being originated or caused. For instance, "source of information" is clearer than "source of things".

Common error

Avoid attributing something as the "source of" an issue when it's merely a symptom or contributing factor. Accurately identify the root cause to provide meaningful context.
