Expert writing Tips
Best practice
When expressing obligation or necessity, prefer using "should", "must", or "need to" instead of "ought" after "reasons" for better clarity and grammatical correctness. For example, use "reasons should" or "reasons must."
Common error
Avoid directly pairing "reasons" with "ought". "Ought" is often perceived as archaic or overly formal in modern English. Instead, restructure the sentence or use alternative modal verbs like "should" or "must" to maintain clarity and grammatical accuracy.
