Ludwig's WRAP-UP
In summary, "or secondly" is a conjunctive phrase used to introduce an alternative or additional point, typically following a "firstly". While grammatically acceptable, Ludwig AI notes that it can sometimes sound awkward, and indeed other options are more frequently used. It is often used in scientific and news contexts. When using "or secondly", ensure it follows a clear "firstly" to maintain parallel structure. Alternatives such as "or in addition" or "or furthermore" may provide a smoother, more formal flow. It's important to vary your conjunctions to avoid sounding repetitive. Be cautious about overusing the phrase. Given Ludwig AI's suggestion of potential awkwardness, consider if a more straightforward alternative might enhance clarity and readability.
